Weight is not the only problem, the risk fire is also a big concern there have many of the EV,s that have caught fire due to breakdown of insulation between the cores there have been extensive studies done on them and also battery storage units for solar power and they all have the risk of fire 🔥.

You make a valid point, not that gasoline isn't a fire hazard as well, but probably burns at a much lower temperature than a shorted battery that can reach temps high enough to vaporize metals. Anyway, I think we all need to consider that today's lithium batteries can and do literally explode when ruptured. I have to wonder how they are going to protect them and the passengers when these vehicles are involved in a serious accident, especially with the added weight.

Lots of things to consider if buying an EV. At some point in time, there will be a variety of used ones for sale. Then there will be a LOT of things to consider. Best thing to do at that time will be to just say NO!

Hmmm. Maybe that
might cause people to drive more cautiously......
Nah... There will still be idiots.
Not to mention simple wear and tear on the roads.

Has anyone thought about the tire life on an EV?
Just as important...the life of the road systems. All of our cars will be as heavy as trucks.
That's going to bean infrastructure nightmare.
Every tire has its weight limitations so a 1,200 pound weight limitation is not going to cut it on a 5,200 ev.and changing the subject a little.my wife has a 2017 tundra crewmax with a 5.7 gas engine that gets about 16.2 miles per gallon on the highway.i there any particular chip I could add to it to increase the mileage cause it's killing me on the gas.
Newton's second law of motion describes how force is related to mass and acceleration where Force = mass times acceleration. In simple terms, when you get hit by something going fast that is heavy....it's going to hurt, really hurt.
If I were in my car, I would rather get hit by a guy on a bicycle going 30 mph than a cement truck going 30 mph. The cement truck is going to leave a mark..!

In addition to the issues mentioned, I think government is just beginning to realize that the electrical generation and especially distribution is going to need to be upgraded substantially (I recently saw an estimate of a 25% increase) to support charging if there is a mass movement to EVs. Those types of upgrades often take decades rather than years because of the permitting and approval processes. Add to that the cost of EVs, the cost and availability of replacement batteries making older used EVs essentially worthless, plus the fire considerations, and I think we’re quite a number of years before a massive switch to EVs, regardless of optimistic government “regulations” in certain areas mandating movement to EVs.
Ask a fireman what they do if called to an EV fire, and the answer is nothing. They just have to wait for it to burn itself our.

When I was in Florida I had a used dressed E-150 conversion van, I thought it was heavy by the way it drove.
I took it to the nearby county truck scales one day, somewhere around 5,000+ I think. I was surprised.....
(At least it had a 351W 4bbl in it.)
PA may register based on weight also. I don't remember Florida.
Living in PA, I pay a set fee for a passenger car and a SUV. I've never wned a pickup so cannot say if they or medium sized vans are registered according to weight. I do not think they are. Large trucks like delivery trucks and box trucks may be.

There's another big problem/concern with EVs: the weight. An EV weighs up to 3,000 pounds more than a gasoline-powered version of the same car. This is a real concern is one of these runs into another car. It is also a concern where the weight of the car is important - like in a parking garage. I think we all have to back to walking and riding bicycles.
https://www.axios.com/2023/04/28/evs-weight-safety-problemsA big concern with EVs in California is the issue of charging stations. Many people in California have installed high capacity, rapid charging stations in their garages to reduce charging times to an acceptable level. Many of these people have also installed solar panels to reduce the cost of charging. However, it is also the case that many Californians live in apartment complexes where installing rapid charging stations and solar panels is not an option. Mandating EVs as California has done is not a half-baked idea, it is completely baked.

They have the suspension worked out and the electric motors can act as brakes.
