Passed first time on 4 wheels back in 1981 (yes, I'm an old fart!) when driving standards were so much higher than today and pass really meant something... hold on, we're not talking about O-levels/GCSE standards here are we?
Also passed first time on 2 wheels a few years later (about 20 to be precise) where the road-awareness I'd developed in the car proved helpful in learning to ride the bike.
I passed my driving test at the first attempt in 1982 after only six lessons. I took and passed my bike test back in '95 after doing a 3-day course, with my only previous bike experience being an hour or two to do my CBT a few years earlier. My first (and so far, only) bike was a VFR750 FL. I look forward to getting another one when I leave the mob.
Passed first time in '95; had three weeks leave, block booked some lessons and my test, my Instructor was ex-Army (and actually had Port and Starboard tippexed on the steering wheel!).
Did my bike test in Gibraltar in '99; one theory lesson followed by the theory test. Three practical lessons followed by the test. Cost me Â£75 all in (plus Â£20 for my licence). Bunch of cowboys, but I got a UK-accredited licence out of it (converted it via DVLA when I returned home).
