Sorry (but not really surprised) to hear about the fatality aspect.
That's the reason I'm such a late adopter, I always preferred the inherent safety factor that a car will provide.
I'm in a similar position (2 kids; 1 under 3yrs old, the other not quite 1yr yet).
I get a buzz mainly from the cost saving which goes directly into providing for my family.
I also enjoy travelling to Glasgow (via all the backroads) to go to the gym trying to see how close to the 'perfect' time I can achieve - believe me, its not about how fast I can go, its avoiding slowing down too much.
I've had a couple of spills caused by
on the road, but thankfully, because I retro-fitted a stout crash bar, all I walked away with was a bit of embarassment, and a lot more knowledge.
What the bike represents to me was the challenge that driving used to pose, constantly re-learning and re-evaluating your skills (such as they are), all at a cost which is also reminiscent of how affordable motoring used to be.
Never has my late Father's words rung more truly - when I passed my driving test he said "treat everyone else on the road as if they were a bl00dy idiot - you'll either be correct (and relieved) or wrong (you can apologise later)".
I am very, very careful.
