OK, I have looked at this petition and I will not be signing it because:
200,000 EVs per manufacturer should be plenty for each of them to work out the bugs and develop economies of scale and compete directly with ICEs. Yes, I know that the oil & gas industry gets gargantuan taxpayer subsidies, and I would enthusiastically sign a petition to eliminate those.
Another reason is a tinge of guilt. I could apply for special a white sticker here in California, to take my single-occupant EV in special freeway lanes originally reserved for multiple-occupancy vehicles, a privilege that fosters resentment amongst drivers stuck in traffic, many of whom cannot (yet) afford the premium of an EV. Also, I am a free-rider on public roads which are (partially) maintained through the gas (petrol) tax which I do not pay. Somewhat separately, my solar panels also come with taxpayer subsidies. All in all I am well coddled by other taxpayers, most of whom are probably poorer than I, and that does not sit well with my conscience.
So no, I will not be signing this petition.
