A M3 yearly renewal in Michigan in over $500. How is that not a solution to the road taxes being avoided? 12,000 miles a year at $3.50 a gallon and assuming 35mpg is only $1600in gas costs. How much of that would really be taxes? I know non-EVs don't pay anywhere near close to hundreds of dollar to renew the registration yearly.
