A brand new Tesla is about half the price of a similar (>400hp) car I guess.

I think there is a fair chance that some of the tax there is just a simple luxury tax, with accidental relief on the Tesla side (as opposed to a proper pricing of externalities).
I would say you'd be correct if the benefits applied solely to Tesla vehicles, but not in this case.
The nice subsidies on expensive electric vehicles may or may not leave a bad taste in the mouth of voters there (I haven't tried to figure out what public sentiment is).
I could not find the answer to this with some quick googling. I too would be interested in the answer.

"Heavy trucks obviously cause more road damage than cars, but how much more? According to a GAO study, Excessive Truck Weight: An Expensive Burden We Can No Longer Afford, road damage from one 18-wheeler is equivalent to 9600 cars (p.23 of study, p.36 of PDF)."

With regards to your point to taxes, remove the per-milage tax and charge a flat per-vehicle rate based on vehicle class, distributing the cost to trucks more than to passenger vehicles.
