I hired a quad bike in Santorini. On the drive between the hire shop and the petrol station (2 blocks) I accidentally got confused about driving on the other side of the road, drove into a tree and my ring finger ended up at a right angle to the rest of my fingers. Also wrote of the bike. The entire nearby cafe descended and took me to the local medical centre, where the orthopaedic surgeon had a broken arm and had to talk an intern through realigning my finger. I then spent the next 3 week beach hopping holiday with a plastic bag over my cast. Tl;Dr don’t hire quad bikes.
