Yes EV owners are freeloading. Trolley Buses were all electric and had to pay the same weight RUC as a diesel bus so it's time for EV owners to pay RUC as well.
These RUC myths need to be crushed.
Road damage goes up exponentially with the weight of the vehicle. One heavy truck driving on a road does more damage than a single car does in months of driving on the same road.
The RUC on cars could be seen as a subsidy to enable trucking, and its not without purpose, trucks and trucking are integral to our economy. The RUC was always a fuzzy cash grab, and was never a fair way of charging for the road.
In actuality the RUC and income tax and GST, and cigarette tax and all the other taxes are just a way of filling the coffers to pay for the goodies. We have a new expense now, carbon emissions, and we need to share the cost of bringing it down. Bickering over a single tiny tax is silly. We need to set goals and then enact policy to get there.
The government just gave a tiny rebate to EV owners on RUC because it was incredibly easy to do and gave them good 'optics'. In reality it does next to nothing and costs next to nothing.
