Well exactly (on what they get out of a scooter, rather than the insurance!)

But as most cars now have locking caps these are the last resort it seems. And it also sounds like maybe these are more than opportunists, so several scooters' worth would fill a tank.

It seems petty to report to the police, but the SNT are keen to hear about such things as it helps them build a pattern and often these minor offences lead to people involved in more major stuff
