I agree with all your points. Still, countering them: - If it's stressful it's probably not a good idea to speed in the first place. I.e. don't go fast if you're not feeling safe. - Granted, but then again I'm not convinced that I'm very, very evil (if you talk about being green) or wasteful (if you talk about saving money) if I go 240 and use 9l/100km if there's someone driving a Dodge Ram with 130 on the right lane. In addition I consider this a limitation of technology, that might/could/should(?) go away w/ time and incentives to the industry. - Depending on the distance I'd agree. I'd argue that I'd be a lot faster on a 400-500km route, but for the ~usual~ trips it doesn't matter much. On the other hand, if the argument really boils down to 'let's get reasonable fast and safe to X while saving energy and removing the individual factor of going there in different ways': Might I suggest to look into trains for that usecase? They are actually quite good in DE and outrun cars/using the Autobahn in a number of cases. Public transportation vs. individual forms of travel.
