Rexicon1 posted:they arent wrong Along with California, a dozen states allow non-carpoolers in carpool lanes, either through tolls or by letting solo drivers enter the lane with qualifying clean-air vehicles. California’s program is aimed at reducing emissions by incentivizing the purchase of vehicles that pollute the air less. But the Federal Highway Administration said Virginia and California are the only states that allow single drivers and have lanes failing to meet federal standards. In Virginia, the slowdowns are occurring on only one freeway: I-66, outside the Beltway, FHWA said.

carpool lanes can have a decent effect on commute time in minneapolis and it doesn't make much sense for most people to carpool. so you can buy a mnpass and pay a toll to use them and that seems like a reasonable alternative use.

no number of hov lanes will make 101 through the valley not suck. it would probably still be overcrowded if you literally made it a double-decker all the way from 880 to redwood city actually, does anybody ever do that? embrace our dystopian automobile-centric future by making a second layer of freeway going in the same direction just to reuse space? i guess you'd have to shut down the lower freeway completely while you built the upper deck, which would be pretty prohibitive

what if I told you you could get on a google bus, it picks you up near your home, it'll take you near your workplace, it only costs a few dollars per ride, you don't have to plan too far in advance, AND you don't have to work at google to do it? It's called a bus, and it pisses google off to no end.
