I haven't passed yet. I'm looking at just how practical (or not) moving over to a car would be financially as it's something I may have to face. It's not really enticing moving from a high performance sport bike to a fairly medicore car and having to pay double the insurance.
Pass your test, wait a year, then get a car. That way you'll have the 1 years driving experience which does make some what of a difference to insurance. Put your parents on the policy.
Stick to the bike for now.
