Actually the car is limited to 155mph They Who Know figured this was the sensible speed to limit it at. But who actually wants to drive at 155? Maybe those who want to drive fast would drive faster if it wasn't limited to 155. And those who want to drive slower...nearly 100 % of the population..want to drive slower. Maybe a top speed of half that would suit 99%. Or 2 std deviations. I rarely go over 125 mph. And only when I am being an idiot. I understand Elon said the roof rack on MX is good for, no, guaranteed for 140 mph. Why would you drive with a roof rack at 140? I suppose I might have done when I was a bigger idiot than I am now. Would you carry kayaks up there? 2x4s? 4x8 ft. plywood? Mother-in-law? Perhaps it is just to compete with others in the market, but the same question applies. Why? Perhaps it is because they can. (build a car that does 155). But since they can possibly get much greater speed from S and X, why limit it so it looks like you can 'only' do 155? I think there is one basic area you can legally do those speeds in Australia. (Northern Territory). And Germany. Where else? Antarctica? Perhaps the cars are designed to be sold to idiots. BTW, in 6 months on the 'other' forum, I never copped a McLary bashing. Idiot, lol. What he missed.
