ooh Den, if it's the lad in question who was on TV a couple of weeks ago, I wish him all success and fortune (if it wasn't then I wish the same for your son's pal)
Prudie - training can help. OK it's never going to protect you from the most serious idiot, but motorbike training is SO different to driving lessons in a car. As I say, my mate has been a biker for 40 years and only had one minor accident. It's all about risk reduction.
If we all stopped doing things that had a risk attached, none of us would ever do anything.
I know how you feel, went thru all that too luckily he soon progressed to four wheels.
In your son's defence he does have a point the traffic on the A13 in the mornings is horrendous and the bikes do get thru fairly easily and returning home same route on a Friday after 3pm must be a nightmare for everyone.
