New riders worry the hell ut of me too, i have a couple of mates who see my bike and then say " i am going to do my test and get a bike" now that scares me to shit, mainly because if anything was to happen to them then would it look like me who led them on and would they still be here if i had not led them into it.
So fart none have moved into biking, i ride with lads who already had bikes.
