From our house we can see one of our neighbour's driveways. An elderly couple live there and only he drives. Almost daily, he reverses out from his driveway very quickly and (presumably) without looking causing a car coming down the road to slam on its brakes and honk their horn. In the past year, there have been two collisions because of this. Often when he's beeped and both times when there's been a collision, the gentleman gets out of his car and begins to yell at the other driver - stating that they went into the back of him and are therefore to blame - obviously this is not the case because he was reversing out of his driveway so the other driver had right of way.
Today, my husband went over to help him with something that we noticed him needing that's completely unrelated to driving. As I mentioned, we can see his driveway from our house so could see him needing help. My husband came back and said that the gentleman (who is probably around 90) was shaking uncontrollably and is very blind and deaf. We feel that this would explain the lack of care when exiting his driveway and the number of incidents. We've also noticed his car is frequently sporting a new "injury".
I'm not usually one to get involved but I feel that this is dangerous. A number of children live on our street and I'd feel awful if he hit one (as I'm sure he would) especially that he has to drive over the pavement to get out of his driveway and he reverses out without looking.
Firstly, AIBU to report this to the DVLA? Secondly, if I should report it, how do I do this? The DVLA website needs a driving license number in order to make a report - and I obviously don't have his driving license number.
