I might as well repeat the overprotective parent perspective. Fatalities are higher if you're in a sedan in an accident with a pickup or semi. There are a lot of trucks on the road as well. Finally, road accidents are the one of the biggest risks young people face. So ignoring the fact that this makes it into an arms race of weight and size, a parents desire for child safety wins against someone's desire to lower car…

You break the arms race by limiting the size.

There are already many incentives in place for smaller cars: * Use less fuel * Easier to park * Cheaper to buy There is generally not much point in having the government incentivize "good" things. Whatever makes them good is already the incentive, and if that's not enough, then there are probably other issues at play that some feel-good government initiative isn't going to overcome.

* Die when hit by a lifted pick up

Perhaps regulations should require all on-road vehicles have bumper and headlight heights compatible with regular cars.

Earlier quoted context omitted.

The government can levy large taxes on new big vehicles just like they did with cigarettes. If the largest SUVs had a 25% tax on it, I think most people will not buy it (basically limiting it). Or if the gas prices went to $10 a gallon, people will ditch their big vehicles.

The government can just directly subsidize the vehicles they like, as they are attempting to do with electric cars. Define a weight and drop taxes/offer refunds for people who buy them, see more of them appear.

The government should tax/regulate things that have negative externalities, and the greater the externality, the harsher the restrictions should be.

Subsidizing smaller cars is a bad idea because they still have negative externalities, just less so. The government shouldn't be favoring driving a small car over walking, but that's exactly what a small (or electric) car subsidy does.

The reason we subsidize EVs instead of taxing gas-powered cars is because the latter is politically unpopular, not because the former is a better designed policy.

Do you drive it on a private road?

Does the road being public mean that my family should have been forced to drive two cars, thus polluting more, all because of some people who can't stay out of other's business? I understand the argument here, but I think it's bad. Government does get a say in what is driven on roads: safe cars that are often inspected and pose less danger to those around and inside them. That's already a lot of restriction, now we l…

You're depicting one side of a question with a practical example ("more pollution") and the other side as though they are simply assholes ("they just can't stay out of other's business"). There is a reasonable version of both sides.

I've wondered if some moving violations should have a vehicle weight multiplier. We police speeding and failure to stop mostly because those actions put others at risk. Heavier vehicles pose an increased risk, so maybe they should be fined at higher amounts?

Do vehicle insurance rates factor in car size? I would imagine that larger vehicles result in higher payouts to 3rd parties in collisions. Maybe it is canceled out by a decrease in payouts to the policy holder.

I believe the government should increase yearly registration costs exponentially based on lower MPG. If you get 10-18 MPG... you must pay 10 times the registration fee that a 40-50 MPG hybird pays.

As long as it's measured by MPG per occupied seat. Our family fills our Dodge Durango and gets better MPG per occupied seat than a single driver Smart car.

20 MPG * 6 > 42 MPG * 1

A larger vehicle full of passengers is often more efficient than a smaller one. Are we going to regulate minimum passengers per vehicle size? I'm not sure this proposal solves the intended problem in a meaningful way. I'd rather see hefty taxes on fuel. This might yield better incentives toward urbanization, alternative transportation, and mass-transportation infrastructure.

What happens when people see the high cost of gas and switch to big electric cars instead?

> There were 35,766 fatal motor vehicle crashes in the United States in 2020 in which 38,824 deaths occurred. This resulted in 11.7 deaths per 100,000 people and 1.34 deaths per 100 million miles traveled. The fatality rate per 100,000 people ranged from 4.9 in Massachusetts to 25.4 in Mississippi. The death rate per 100 million miles traveled ranged from 0.63 in Massachusetts to 1.97 in South Carolina. Footnote

This is just an overall death statistic in cars, not ones where the size of the car was actually to blame for a death. Given such a small number, I think the government can forgo regulation.

Edit: Yes this covers pedestrian deaths

There is an environment cost to manufacturing a car, any car. Sure in the long term, more efficient is better is better for the environment, but you want to amortize the harmful costs of manufacturing (and discarding) cars by getting as much use as possible.

In other words, a policy like this would require a fair bit of balance (make sure cars stay on the road for long enough), otherwise it risks increasing pollution.

The conflict here is that while bigger vehicles are often safer for the occupants, they are way more dangerous for anyone not inside a vehicle that big, especially pedestrians. Namely, if you get hit by a larger vehicle, you're less likely to tumble over the roof like what would happen with a sedan and instead you get knocked over and crushed.

And of course, "the fact that this makes it into an arms race of weight and size" is absolutely not something that we can ignore. This is a perfect example of a situation where everyone acting in their own rational self interest is way worse for everyone, and is why the government should be regulating the size of cars.
