I have a feeling there were also some things such as bonnet to engine clearance that it would fall foul of without things like pyrotechnic rams to increase distance and change angle for pedestrian impacts.
Either way if the regs result in a load of needless tech, bloat, weight gain and reduction in the purity of what is a more old school driving experience I wouldn’t be interested in buying one even if they were to contine being sold in the U.K. My daily driver, a company BMW deciding to throw the anchor out of the window at the merest sniff of a kerbside wheelie bin is enough to convince me of that!
