anyone who has two cars can only drive one at a time
and generally its one for work and the other for any other time

all of those people need to have two lots of regos and insurances
so in the end the only extra cost is the engineering

years ago I used to work on many rally cars and the club rego was always a pain in the butt

club rego used to be only for race cars and u could only do a minimum amount of kms a year
