Surely, anyone who lives here knows, anyone using their vehicle and does something wrong, then the owner of said vehicle is liable, one of the first things you learn. I had an English friend look after my animals for 2 months while I,ve been in Nepal and India, and even though I trust him, still put keys of car and scooter in safe, so noone could use them. Better to be safe than sorry, you,ll just have to pay and put it down to experience
