People should walk as far as they are willing to walk.

As i mentioned in my other post. Thats not far for most people. More than 1/4 mile and people will not hesitate to get the car

I'd say most people in overly car-centric areas balk at walking from the far end of a Walmart parking lot.

With the continued shift to EVs, petrol taxes just don't make sense as a form of taxation to pay for roads. I think we should be shifting entirely to a gross curb weight tax for all vehicles. The fourth power law states that the greater the axle load of a vehicle, the stress on the road caused by the motor vehicle increases in proportion to the fourth power of the axle load. Meaning heavier EVs cough hummer , are doi…

New Zealand plans to charge road user charges for EVs next year AFAIK. This is a per km tax, though don't believe it has a weight consideration

> Indeed, the scale of these emissions is significant. Particulate emissions from tires and brakes, particularly in the PM2.5 and PM10 size ranges, are believed to exceed the mass of tailpipe emissions from modern vehicle fleets, as per a study published in Science of the Total Environment this year. This simply cannot be true. Tailpipe emissions have more mass than the gasoline that gets burned. A car uses several l…

Exactly. Not saying this is good news either way, but I can go multiple years on a set of tires, and majority of the mass is still there when I go to charge tires.

Perhaps they mean just the mass in the pm2.5-pm10 size spectrum?

The positive externalities are even more enormous, which is a problem for environmentalists.

>The positive externalities are even more enormous What do cars specifically positively provide? NOT including the positives that exists due to constructing infrastructure around that mode of transportation (artificial issues).

Mobility; unfortunately, the public transit infrastructure in the US isn't that great and the sprawl means that cars have become a necessity.

Many areas simply can't be served efficiently by transit.

Being by far the most convenient way to travel from home to pretty much any random location.

Speaking from the Netherlands with a relatively good public transit system.

The car shaming mindset makes sense if you live somewhere like Japan where transit is clean and fast, and you don't have problematic people who assault other riders and do drugs. As a family man living in a large American west coast city, there is no way I would ever give up my car lifestyle.

Cars are the leading killers of kids in America.

So? No matter what actions you take, _something_ is going to be the leading killer of kids. By itself that statement means nothing.

I was in the market for a small electric city car and found out that we're not allowed to have small cars in the US. Europe and Asia have really nice small city cars under 2,000lbs but none of them are available here. I believe the smallest car sold in the US is the Mini Cooper around 3,000lbs. I actually ended up with a souped up street legal golf cart and it's worked out well for my purposes of picking up kids and…

Doesn't really matter in any case. The bulk of the problem is 5000lb+ vehicles. F150, SUVs like Suburbans, etc. etc. I'm not even sure if people are using these big vehicles to carry their families around, its probably just single-person drivers in most cases. I'm not even sure how to approach the weight problem. We have plenty of cars in the 3000lb or 4000lb range but more-and-more people are pushing 5000lb+.

A tax during annual registration based on axle weight to the fourth power times the number of miles driven since the last odometer reading.

https://en.wikipedia.org/wiki/Fourth_power_law

There are some horrible states without annual inspections, but they should be federally punished until they comply. If we could force every state to have a drinking age of 21, using access to highway funding, then there's no reason the same thing couldn't be done for vehicular taxation. It would increase state tax revenue anyway...

IIRC there is a push in some areas to switch to e-bikes; while they carry less, you also don’t need a CDL to ride a bicycle and there is a chronic shortage of CDL drivers.

There's no shortage of anything except training and wages/benefits. At some point, companies are going to have to bite the bullet and start training their own employees. The horror!

There is a legitimate lack, partially because the federal guidelines for holding a CDL rule out anyone who uses marijuana.

Has anyone here ever lived near a freeway or even moderately busy road? I made the mistake of renting next to the freeway. Noise was perfectly tolerable, but I could not use my back porch, because after just a few weeks, everything had a fine coating of black dust. I could not keep my windows open in the summer. I was certainly breathing this vile shit the entire time I lived there. This doesn't surprise me in the le…

Do tires shed more dust at higher speeds? I wonder if this has always been a known but unstated problem, or if increasing highway speeds are causing it to get worse.

They should as cornering and braking exerts a higher force on them, so they should wear faster.
