There was an article in the business section of my newspaper yesterday which said that a bipartisan bill is being considered in the U.S. House of Representatives that would impose a yearly $130 tax on all electric-only powered vehicles. It would require states to impose that tax on top of their vehicle registration fees and pass the money to government, along with the usual 18.7 cents per gallon fuel tax. Hybrid vehicles would be charged only a small fraction of that fee. It was noted in the article that very few ICE vehicle owners pay as much as $130 a year in gasoline taxes. This tax is to help pay for the maintenance and repair of highways in America. It was also noted that the tax hasn't been increased in about 20 years. It seems likely that this bill might pass in the House, but its fate in the Senate is uncertain. If it passes both houses of Congress, President Trump is very likely to sign it into law.
Needless to say, electric motorcycles were not mentioned as being exempt in the proposed law. Unfortunately, if this law passes, I wouldn't be surprised if motorcycles end up being lumped into the electric vehicle category and also get hit with this tax each year, even though electric motorcycles have a vastly smaller impact on highways than electric cars or trucks.
