This is an interesting topic, I think the three wheeler may help,it is expensive but judging by my 2 boys (and their friends both male and female ) enthusiasm for it ,this may draw younger people in . Against this is the fact that you can't treat them in the same way as a 'normal'car, most of them never consider doing any kind of maintenance. Also a lot simply find the costs of any sort of car too high and loose interest.
