I think it’s fairly irresponsible. Rachel was bang on suggesting that the longer the rope, the more chance there is they’ll hang themselves with it.
Getting rid of the metaphors, whilst you can kill yourself and others at 50mph, you’re more likely to do so at 150mph and if the temptation’s there, younger kids are more likely to try it.
I drove at 120mph last summer. Empty, dry motorway and wanted to see my sick (D&V, no heart-wrenching excuse) son. Being older, I’d thought about the maximum speed, other people etc as well as a few years experience telling me that faster would have been more stupid. If I’d had such a fast car at 19 I’m fairly sure I’d have found frequent reasons to get somewhere quickly.
