I say use those failed tests as omens...keep death off the roads..the highways are dangerous enough without adding to it.
Stick to the buses you know it makes sense.
Btw I passed my motorcycle and car test 2 weeks into my 17th year
Then passed my HGV 1 at 21....that's what us men do I suppose
my misses failed 5 times, shes been driving in the UK 7yrs now without causing or being involved in any bumps or crashes and shes been driving OVER A 100 miles a day
