I said nothing about safety. I just said it should be considered a different class of vehicle if it meets certain characteristics. SUTs are great for camping, for hauling surf boards & kayaks (possibly with a rack) and tow just as well as pickups. They don’t have a full-size bed, so they’re worse at most jobs, though the larger cab does mean they can carry more workers at once. It’s a trade-off: get worse at most work-related tasks, get better at personal tasks and thus reach a wider market.
Not directly, but they improve the low-power modes substantially, and using the low-power modes for longer times is the solution. Inverters aren’t strictly needed, but they do make it better.
