Good points, this probably explains why I’ve not heard much about hydrogen fuel cell cars since modern electric cars picked up. Ultimately the hydrogen cars seem no worse than conventional ICEs, but given that EVs are developing pretty well now there’s not that much need for the hydrogen ones anymore.
Because most people who don’t like nuclear energy think we can all change everything to renewables right away. This is obviously not possible (otherwise countries not bound by the financial interests of oil companies etc. would have already done it); the real options to cover the gaps in renewables (until their tech develops) are nuclear or fossil fuels. Nuclear is significantly safer and less polluting than coal.
