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 carbon emissions.

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.

Unfortunately there are also incentives against small cars [1].

I'm also curious why (required) speed limit regulators aren't a thing, especially in cities. Why are cars physically allowed to go more than 25 MPH in NYC? I thought speed limit regulators are required on some kinds of scooters and electric bikes. Cars are a lot more dangerous. It's not that I think NYC or the US is very progressive when it comes to dealing with potential car crashes (we aren't) but I'm also curious…

Woah, thanks for the link!

No substance. How could the government limit the size of vehicles? > Companies will never voluntarily reduce their SUV sizes unless outside forces pressures them to do (like $10 oil). If oil (say, brent crude) goes to $10, something has gone very awry.

Of course the govt can limit vehicle sizes, and already do, in both width and weight, at least, to fit the roads.

Within those limits, I think they should push for more environmentally friendly vehicles through taxes.

But not just fuel taxes, which might not give the desired incentive 'curve', and in any case still penalize even the most economical vehicles.

But directly; per kerb weight, per mpg, per co2/mile, etc, etc.

Why can't they government fix my pet peeves? This kind of thinking is what's leading us to a prison society without privacy or freedom, one little whiny step at a time. The government should do as little as possible, and the least at the federal level.

The government built the roads, to a specific specification of assumed car sizes. If cars get so big that they break these assumptions then roads start getting blocked, or you start to have streets that some cars are too big to fit through (already happens in older cities in Europe) - and this would adversely affect other people. What next, are speed limits also leading us to a prison society, because people don't ha…

Exactly, if I can afford it, can I drive a tank around that hogs two lanes? Why is that illegal? Why is nobody protesting the government banning Juul?

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.

Sure. The post says nothing about that though. Just a bunch of baseless assertions about cars being bigger than ever, but the '90s versions were super comfortable. OK.

> Consumers who fear for their safety and buy big cars and rest assure nobody else will be driving an even bigger car.

Sounds like a middle-schooler banging out a 3-point persuasive essay asap so he can use the rest of the time to play drug wars on his ti-82.

Right, but make sure that all externalities are properly payed by fuel/road/vehicle taxes, so individual incentives are not distorted by not having to pay those.

I'm the oldest of 10 kids. My family needed a 15-passenger van to travel. Why can't the government stay out of my business?

Why is van classified as a car? It's more like a mini-bus than a car.

It's a private vehicle, not much larger than a pickup. The Ford Transit is excellent, by the way.

While I applaud the motivation, it is incorrect (at least in the US) to say that government "should" limit the size and weight of cars as this suggests that it does not already do so which it clearly does. It is also incorrect to state that anyone is forced to buy a big car. Even in the US, there is a selection of sub-compact cars that are fun to drive and tend to be on the cheaper side to buy let alone drive. I'm al…

What meaningful limits does the US government put on size/weights of cars? A rivian R1T has a gross kerb weight of like 9000lbs, the new electric hummer over 10000. With the move to electric cars, especially large commercial ones, they will generally get a lot heavier as batteries plus motor is typically much, much heavier than combustion engine + gas tank.

A quick google says you can pretty much drive anything on a single axle in the US so long as its 20,000 lbs or less- thats so huge there might as well not be a limit...
