Have you ever slid into a ditch? I have a couple times. It's a fair amount of work to get the car out of the ditch. With thrusters, you only need a couple seconds to get out of the ditch and back on the road.
Is that where we are on the technology curve, putting rockets in cars to get out of a ditch? I can think of about a dozen simpler and safer solutions if getting out of ditches is the main use case. Anyway isn’t FSD supposed to keep us out of ditches to begin with? If we have to reach this hard to find a justification for a rocket car, then maybe it’s not really justifiable.
Since the “rockets” only have about a second of propellant, hopping bodies of water with unknown depth seems like a bad idea. Or is this car also supposed to be a boat just like the cybertruck?
I guess as long as we’re thinking up increasingly outlandish use cases, how about being able to park at the top of buildings when there are no parking spots available. Or being able to hop over the parking gates at theme parks. What about bypassing the speed limit at school zones or hopping over stopped school buses. Oh and no more waiting for draw bridges or railroad crossings. The uses really are endless!
