I've been watching Sandy Munro's video as per one of the above links.
For someone who makes his living dissecting and critiquing automobiles, I am astonished that, at around the 12-minute mark, he complains that there is no self-opening/closing front hood/bonnet, except from 3rd-party modifiers.
One of the here-we-go-again recurring discussions within TMC's early years addressed just this. And then, after a few back-and-forths, one cognoscente would step in and state "Because the laws do not allow it!". And, apparently, not just USA laws but EU - and the rest of the world - as well.
So.
Is this just one more "Must be so 'cuz someone on the internet said so" myths, or is it specifically the case? I come down on the side of "It Likely Is", because it is such an obvious, oft-requested modification that I find it inconceivable that at least one manufacturer - possibly just one niche player - would offer it were it allowed.
