I rode bikes in the seventies and I had a few spills mostly self inflicted or weather related but there were a couple caused by car drivers. Never been seriously hurt though. I've done much more damage to myself skiing!
Re the oil filling, I spent 46 years in the motor trade and I did once fill one up without draining the old stuff! In my defence I realized before driving. The more times you do a basic job, the more chance there is muck it up!
