Dealing with government and taxes there is one additional factor to consider. The government can give tax cuts to targeted groups if they consider it beneficial to society. So let say the truck has a $5000 tax to pay for yearly wear and tear on roads, but they also get a $5000 tax cut to reduce costs in the transportation sector. That will leave cars to still pay their road tax, even if in comparison they would be a tiny portion of the total road tax.
