I'm now 62. I've owned an auto for about 8 years of that time. I've not owned one for 27 years, and haven't driven for 26 years. I suspect that I'll never drive an auto again. I did have some pretty amazing auto trips, however, including one across the USA from the west coast (Washington State) to the east coast (Massachusetts) in a 1963 VW van with all my belongings inside (top speed of 60mph on the flat with no headwind, and the bicycles off the roof rack). Commuting was always Hell on Wheels.
Since the age of 5, I've always had at least one bicycle (at most 4). So, that's about 57 years of bicycle riding. I suspect that I've done more than 300,000 miles on a bicycle, and not a 5th of that driving an auto.
The only crashes I've had are when racing bicycles (unhappy but part of the sport) and, being run off the road twice in the UK (in 27 years). Both of the later cases were boy racers in country lanes.
Working in Oxford, I've seen some pretty atrocious bicycling. A fair amount of pretty bad driving too. I suspect that there are people in cars listening to music, using mobiles, etc., who aren't completely aware of their surroundings. On the whole, however, the rude drivers are outliers. Still, defensive cycling is the only way to go. Hope for the best, but expect the worst.
And I see some hope for Oxford, at least. In the mornings and afternoons the traffic is at a standstill. And the periods when this is so are getting longer. So, no competition on the roads for people with bicyclists. 6-8 minutes to college by bicycle; 30+ minutes by bus. It used to be the case that unmoving traffic would produce lots of nasty fumes. But no more. I've been told that modern non-moving motorized vehicles now have auto cutouts for their engines.[1] And I have noticed fewer fumes in stalled traffic.
So, let's make it a basic right in the UK for everyone over 18 to have an auto. With luck, that way there will be no competition on the roads for bicycles at all.
Best wishes,
Bob
[1] We seldom even get lifts by automobile. But, we went with some friends to a lunch party in the south and I asked what was wrong with their car that caused it to keep cutting out. ;)
