Should governments be doing more or less for the EV industry?

There are certainly some very different opinions with regards to government involvement in the EV market and whether indeed they should be doing more are doing less. Are governments around the world investing enough or are they investing too much money in the industry?

Are taxpayers losing out in what some argue it is a false market or, quite rightly, are governments just giving the industry the assistance they have given hundreds of other industries over the years?
