omegas are sh!te in the wet.
I knew that before I bought ours Steve.
The sheer physical size, combined with the weight, drivetrain arrangement, and suspension setup told me all I needed to know before I even got behind the wheel.
Anyway, got it straight back with a reverse twitch of the front wheels. The missus was amazed, didn't know what even happened. But she's never driven a rear wheel drive, and neither have many youngsters these days.
I'm sure that's why so many of the kids screw up these days mate.
All this front wheel drive, abs, traction control, electronic stability 'dangle berries'.....it's just that, it's 'dangle berries' because it isn't making a driver better....it's just compensating for the shortcomings.
We should forget all this theory and multi choice questions for the driving test, and do the following....
Take one old school M3 with bugger all electronics
Insert test candidate behind wheel
Make test candidate drive in central london (or any other crowded city) for 8 hours in the pissing rain/snow/ice
If they get through the day without screwing up (too much), then they've earned the license!
and there's no substitute for experience.
Spot on

I had a slight advantage as I started riding in competition from an early age, but I still f**ked up more than once when I finally got on the road.
Like you say, the ONLY thing that taught me (and still teaches me today) is experience....and there is NO test for that and NEVER will be.
