Ok so who has modified their EV for longer range? I have been doing some aeromods to my Leaf. Here are some test results: https://www.youtube.com/watch?v=w5OVB4peSIA Approximately .2mi/kwh at 65mph gained on flat ground or about 4 miles of extra range over a 20kwh battery charge. Of course this should increase with speed and also will result in increased regen. Vitamin J fucked around with this message at 20:49 on Feb 24, 2017 |

Cover the wheel arches. In the rear only, hopefully goes without saying but you never know.

Has any company tried the Airbnb model for EV charging? Let folks on road trips pay a modest amount to park in some random driveway for a few hours to top up? If I had a BnB near a large city I would definitely consider a Tesla compatible charge point for guests.

There is charge maps but most driveway spots are free. You can add a spot to the map. Unless you have some magical location though no one is going to want to hang out in your driveway for 2 hours. Below: That is what I was talking about. I have never seen a charge private location but you might be murdered there so who knows. There are 20 around my auto location most just say call first and I will open up the garage for you. Bunch of EV nutters. Elephanthead fucked around with this message at 22:22 on Feb 25, 2017 |

The VW I.D. Buzz has had some more specs released, a few months back, not sure if it has made the rounds.   Dimensions: length 4,94 m, width 1,97 m, height 1,96 m. Wheelbase 3,3 m. Two powertrains to choose from, 111 kWh / 369 hp. 83 kWh / 268 hp. Seems a big bunch of power for the job, but the I guess max rating of the motor isn't necessarily the same as the watts available to the right foot. The draggy flat end will impact range, but 111 kWh will still go a long way. Just need a roof rack for surf boards.

Looks like an electric version of the old VW bus with the modern conveniences of a Flex. I'd buy one in a heartbeat if it was available looking like that and I was in the market for a >2 person vehicle.

More VW concepts, a driveable one. https://www.youtube.com/watch?v=1V0je9WFjRc So much white plastic it looks like a render. It's barely more functional than a 3D render and filled with unrealistic features, but it shows that VW is on their way to somewhere good.

When I was in NZ we rented a campervan and I couldn't help but think it's a no-brainer to make an EV campervan. We drove maximum 150-200 miles a day and stopped multiple times in towns along the way, a 100kwh battery should be able to do that range even in a van. Then most nights you stay in a campervan park and there is a 240v outlet in every spot! The times you don't stay somewhere with electricity you could still plug in when you're doing touristy stuff. That idea probably won't work in the US, not until you can get 300+ miles and much faster charging, but in Europe or the UK it definitely could work.

Campervans in Norway never exceed 20 mph while the driver is filming fjords anyway, so that should help range. Btw, funny to think the T1 and T2 VWs were actually camper vans which families spent the night in, nowadays they are dwarfed by a compact SUV. People of the 1960s were teeny tiny.

blugu64 posted:I'd really prefer actual side view mirrors too Camera-based "mirrors" are probably never going to replace actual mirrors. With a mirror, you're looking "through" the mirror into the distance, so you're focusing on roughly the same distance as looking at the road ahead. With a monitor, your eyes have to adjust to an object right up in your face, which takes time and can be uncomfortable to do quickly. If camera-based mirrors are going to be a thing, they need to do some fancy trickery with lenses and mirrors, otherwise people will just hate it.

The most critical problem with using a camera as a mirror, to me, is that you can't temporarily adjust the angle of view by moving your head. The camera only sees what it's pointed at, and to see anything else you have to move it around.

Both good points. Also, a lens and an image sensor will be less likely to match a mirror in providing useful detail in direct sun glare, although it might be better at night.

EV insurance talk: I wrecked my year-old Volt on black ice a couple of winters ago. Allstate adjuster had never seen a Volt, dealership body shop in buttfuck TN had never worked on a Volt. Allstate authorized $18k in repairs (on a car that at the time was selling used for $23k). They fixed the body and the car still wasn't drivable. After much back and forth with Allstate, I finally got them to total it. I cringe to think that somewhere someone is driving that car. You know they didn't just throw in the towel after they cut me loose.

CharlesM posted:OK maybe a dumb question, but isn't a mirror in 3d where a video screen is not? Yeah, but I for one don’t feel like I get a lot of binocular depth cues from side mirrors. I’m sneaking glimpses at objects that are relatively far away. Another difference with mirrors is that if you move your head you get a different view. This can be good or bad. A couple of nice features screens have are that they can limit brightness selectively and that their size isn’t constrained by ærodynamic/width concerns.

CharlesM posted:OK maybe a dumb question, but isn't a mirror in 3d where a video screen is not? Only the center bit. Anything along either edge will only reflect into one eye. Also at the ranges you typically see things in car mirrors, you mostly determine distance from environmental cues anyway. Also also, many mirrors are convex and that messes with binocular range finding quite a bit.

A mirror is just reflecting all the light going into it. It is a handy result that to look behind you with a mirror your eyes can stay focused similarly to looking through the windshield, whereas with a video screen surface a foot or two away you have to refocus your eyes to the much shorter distance (same reason why I hate 3D movies... too much drat work to keep refocusing my eyes). With a mirror you are in effect looking out the rear window instead of the front, which is similar in terms of focal point (the greater the focal point distance from you, the broader the depth of field too). It would be technically possible to use optics to change a video screen so that it could be focused on similarly to the mirror (focusing past the physical surface, same concept as how with VR goggles you are focusing into the distance rather than the screens an inch from your eyes) but this might seem weird in actual effect, I dunno. Don't they do something like that with the HUDs projected on windshields?

How would you do that technically? I thought the VR model depended on screen-per-eye.

I haven't studied VR optics for a couple of years, but focusing my eyes at different depths involves changing the direction my eyes are pointing as well as lens curvature. The directional pointing, and image translation, is an essential piece of the focal depth sensation, as I recall -- which could be wrong! What optical techniques are you referencing that can mimic different focal points? I know there's research into doing it with polarization tricks, but it's still far from product.

The directional pointing, and image translation, is an essential piece of the focal depth sensation, as I recall -- which could be wrong! Without getting too into it (trying to read up more on this myself), it looks like the technical explanation is a "real image" vs a "virtual image." The former is light rays converging to make an image that can be projected onto something (think a projector onto a wall - once you focus it right, you see the image). The latter is diverging light rays that require an additional lens (your eye) to resolve (such as a microscope - you aren't looking at a projected image or screen, you are jamming your eye into the path of a bunch of light rays that can be resolved when your eye focuses at a comfortably far distance). Most things we look at are diverging images, as light reflects off of objects around us and our eyes, focused at the appropriate distance, project a real image onto our retinas. It appears what with some wizardry it is possible to alter the path of the light rays to diverge in a different pattern that allows your eyes to focus at a different, more comfortable distance, to resolve them. I wonder if there are issues with angle of view that the methods work with, though. I believe a rear view mirror is far enough from your eyes that the individual aim of each eye wouldn't change anything. somebody call a physics major/optometrist in here!

Kind of bad news for the Ampera-E, perhaps good news in the long run.quote:General Motors is selling Opel, it's European division, to the PSA Group. nordic.businessinsider.com/gm-opel-sale-23-billion-2017-3 By now, Opel and Vauxhall are just empty shells. They have a name and an organization, but no own patents or platforms. What does Peugeot get out of this? Will GM sell the Bolt in Europe now? Will you take your Chevy which actually is a General Motor but sort of is an Opel to Peugeot for a warranty repair? Or just get a Tesla?
