If you adopt the user pays principle, motorists should pay more than they
do now,

Based on what logic?
By what magic thought process have you deduced that current rego is too low?


SUV (Stupendously Useless & Vacuous) idiots even more,

Agree.

and truck lines most of all.

They already do.

Cyclists should be paid a rebate as we are doing the rest of you a favour.

There goes that logic again.
Explain to me how you are doing me a favour by riding in the middle of the
road at 20km/h effectively cutting off an entire lane to the rest of use who
have paid to use it?
