a lot of Chinese that came from China in the 80s-90s do have this mindset. that cohort is disproportionately well educated; university education in China more or less rebooted in the late 70s after the Cultural Revolution and those who left the country often did so for graduate and post-graduate studies. as a result, this group was able to land in professional or academic careers and there's a lot of survivorship bias and confirmation bias.

it's not uniform by any means and the expats/immigrants I know with current family or friends in China are starting to see the cracks in the facade and are really displeased with the escalation between the US and China. the politics of this group are still pretty socially and economically conservative because of the aforementioned biases and privileges, so I can imagine that people who are less connected and assimilated more into groups in the US are closer to Cuban expats in political demeanor

New Yunju Mountain Tunnel Group

New Yunju Mountain Tunnel Group consists of five tunnels with a total length of 4,510.29 meters, which is the most difficult key control project along the whole line of the Fuxia High-speed Railway. Tunnel rock changes are complicated, cave wall rock body stripping, falling blocks, is a hilly area, construction safety risk is high, and the new Yunju Mountain Tunnel No. 3 and the existing Fuxia Railway, Fuping Railway, the new Yunju Mountain Tunnel No. 1 parallel to the established Fuping Railway, from the established Fuping Railway is about 120 meters to 280 meters; Tunnel inlet in the southern end of the southern end of the Fuzhou South Railway Station, below the existing Fuzhou South Railway Station, the terrain is dangerous, and with the Fuxia Railway, the new Yunju Mountain Tunnel inlet, the new Yunju Mountain Tunnel inlet, the new Yunju Mountain Tunnel inlet, the new Yunju Mountain Tunnel inlet. Tunnel inlet, the new Yunju Mountain Tunnel No. 2 exit for the small spacing section; hole on the body across the Sanjiang Highway and the new Yunju Mountain Tunnel, the minimum height of the upper span is about 4.5 meters, with a "small spacing, adjacent to the business line, three-dimensional intersection," the characteristics of the construction of the operating conditions of the complexity of the construction is very difficult.

Wulong River Special Bridge

Erection of the first steel box girder of Wulong River Special Bridge

Wulong River Special Bridge is located in the waters of Wulong River in Cangshan District, which is China's first four-lane high and low tower double cable-stayed hybrid girder high-speed railroad cable-stayed bridge, with a total length of 739.9 meters, a main span of 432 meters, and a combination of 7 concrete box girders and 45 steel box girders, which is the key controlling project of the Fuxia High-speed Railway. Wulong River Special Bridge is located in the waters of fast-flowing water, complex underwater geological conditions, narrow space for construction work, and great difficulty in construction.

Leigongshan Special Bridge

Leigongshan Special Bridge is located in Fuqing City, Fujian Province, with a total length of 2,631.655 meters, which is the key controlling project for the whole line of Fuxia High-speed Railway, horizontally crossing the Shenhai Highway, with a span of 224 meters, the main pier drilled piles with a diameter of 3 meters, and the main pier bearing adopts the spherical bearing with a vertical bearing capacity of 180,000 KN, which is characterized by the large span of the continuous girder, the large diameter of the main pier drilled piles, and the large tonnage of the main pier spherical bearing, etc. The main bridge is located in the windy southeast coastal area, which is a very windy area. The main bridge is located in the southeast coastal windy area, heavy rain, typhoons prevail, the narrow tube effect is strong, the main bridge long tension cable in the wind and rain in the climate conditions will cause significant vibration, wind and rain vibration phenomenon, construction technical difficulties, high safety risk.

Clearly you don�t know what you�re talking about. ICE exhaust chemically bonds with rubber, rendering both the exhaust and the rubber inert and harmless. Without the ICE exhaust all of that rubber is just getting blasted into the environment where it causes any number of problems :eng101:

electric cars in city traffic often do wear the rubber harder because of the extreme torque plus stop and go conditions

Well, the pressure exerted on the road surface is the same pressure on the tires (and in the tires also) so the increase of weight increases the wear of everything to the fourth order

The ev tires get wider to maintain the ~same PSI so you don't notice as much

The kid who lives across the street from me just traded in his smaller older truck for a F750 Child Crusher edition. It doesn�t fit in his carport so I guess he�s just going to leave it in front of my house on the street forever.

My crazy neighbor has a bunch of "NO PARKING" and "ACTIVE DRIVEWAY" signs staked in front of her house. She'll go around knocking on everyone's doors if someone parks there. She had someone's car illegally towed once after the police wouldn't do anything about it.

It's hilarious when drivers here complain about how the traffic is bad. My dude, downtown is made up of two lane streets, one of which is used for parking and the other is constantly clogged by cars waiting to get in/out of the parking lane. How do you expect this setup to function, exactly?

Can't remove the on-street parking though, that's war on cars.

simply replace downtown with an open expanse of pavement sectioned into driving and parking areas as needed, then traffic will be great
