Sports cars can be enjoyed (relatively) legally on the street. Quick acceleration combined with very good handling and a sense of connection to the road is a feeling you can enjoy at 55mph. Many people won’t drive their sports cars to the limit, but they are still a more enjoyable driving experience than a regular car for people who care about that.
A cybertruck can’t really haul things, it can’t really tow things, and it can’t be that fun to drive. I hope it’s at least comfortable, but based on my experience with their other vehicles, I doubt it.
