The F150 lightening weighs about 6,893 lbs. That's before you put a load in it. I'd guess a load of pea gravel or similar would push it over that max weight of a guard rail. Hook up a horse trailer to it? Definitely. For the record, the F150 is the best selling consumer vehicle in the US and I doubt that's going to change too much. I appreciate the people in here saying "not all electric cars", but there's absolutely electric vehicles already on the road pretty dangerously close to this max weight. The Rivian truck weighs in at over 7K lbs (7,148 lbs). The Tesla cyber truck weighs in at 6,603 lbs. These vehicles have load space that can accommodate heavy loads. Their curb weight is dangerously close to (or in the case of the Rivian over) the limit that our guard rails can safety buffer.

America has a lot of problems with things like the "Chicken Tax", and the NHTSA regulating automakers for the purposes of higher mile per gallon vehicles, which has started and continues a trend of making larger and larger vehicles with intent to circumvent those regs and make more profit. The whole system is a bit broken, honestly.
