I Had the same idea with power limits, Same as what they have with Bikes, No More then 150KW per ton for Ls and Ps. I did contact the Head of RTA with this idea, As Learners can drive any powered Diesel so long as its not turbo, So they can drive the new VW V12 with 350KW, but its diesel and not turbo.
But apparently they have already trailed this and apparently its not practical.
I dont understand why its not as it works fine with bikes, and again Power limits, I can ride a 1000cc bike & drink, yet i can only drive a V6 cause and not drink.
We really need to adopt what they do in Germany and instructors teach and not the parents, and Leaners start off in the safest car.
As for a comment that mentioned to put rego high on older cars, not everyone can afford 5 star safety rating cars, The government would need to step in and help out like they did in germany.
