I'll spin out around 27 mph in my 1x11 rig, but my commute doesn't have long and steep enough hills for that to happen. Plus, that kind of speed on a MUP gets a bit out of control. Saw a lady changing her kid's diaper on the MUP yesterday. Felt like stopping to tell her she should consider doing it on the grass two feet over, but couldn't be bothered. I mean, if she doesn't care, why should I? Lots of really stupid people around here. Couple months ago I actually did stop to tell a guy it's illegal to fly a kite at the end of the runway where the planes are landing right over your head. His response was "Really?"
