1. Clearly the vehicle backing has total responsibility for the accident "but for"the fact that the owner of the parked car created an unnecessary hazard the accident would not have happened. Hence the car in motion was ticketed for the accident (unsafw backing) and the parked car for creating the unnecessary( hazard).
2. What is the sense of having rules, deed restrictions etc if they will not be enforced. Many people chose to move here because of these rules. Who wants to see an RV, Van car in someone's driveway day after day....worst yet on the streets creating additional hazard and hence risk of accidents, etc
3. For those living in Villas they may not want to give up on the guest parking rule.
P.S. I had a neighbor who parked his car on his driveway until he realized rats where using it at night. Rules serve a purpose for health safety and aesthetic value. If you want to keep The Villages beautiful then every resident has to do their part in either abiding by the rules or ensuring they are enforced. A start would be by complaining to your district superivors
for any violations. Actually the beginning is to acquaint yourself with the rules, etc applying here
