I'm not signing. Taxpayers shouldn't be forced to subsidize the cost of luxury cars for people who are generally more well off than the average family. There are so many better things we can spend that money on. That subsidy was to stimulate demand and thus encourage manufacturers to build EV's. With there being 400k preorders for the M3, demand is not an issue.
I much rather see the real cost (i.e. "social cost") of ICE vehicles reflected in their price and in the price of petrol. Remember the 53,000+ deaths per annum that Elon spoke about in the reveal and the little chart he showed on CO2 emissions? The focus ought to be on urgently putting a price on those costs.
If tax incentives are to be given, the order of priority should be for:
3. Public transport
Lobbying for tax incentives might actually be counterproductive in the long term. As for renewable energy, it has the effect of attaching the stigma that "it can only by viable with subsidies". I'd rather see appropriate regulation than tax incentives. I want Tesla to be viable without tax incentives - that will be best for Tesla and the rise of EV.
