Yeah, except that in my experience, you end up with a group of teenage friends with two cars, which means a race :/

Also doubles the requirements for designated drivers, which increases the risks that someone decides "Im not that drunk".

I broke the 2 passenger limit a couple of times on my Ps, it never made sense when responsibly driving two friends to the local trainstation. I just took the P plates down :/

It's something like that and the one passenger rule is because they couldn't ban it altogether since some are going to work or coming home during those hours from what I remember.
