New studiy shows CO2 bilance of e-cars is worse than that of Diesel cars

Electrical infrastructure is indeed failing more often now, thanks to privatisation, when companies try to generate more income by neglecting maintenance.
Using electrical propulsion at the time being can only be of local advantage, the energy has to be produced somewhere. And while it might help to take the load of pollution and noise from certain 'hot spots', it just puts the problems out of sight.

Next, the millions of tons of copper needed to build the infrastructure with enough charging stations, because you need one for every second car at least, it is not like with gas stations unless you exchange a rechargeable battery completely everytime. Or maybe the charge cyclus can be sped up, but then you need even more energy.
Then you have energy current loss in the power supply lines, over the miles from the powerhouse to the charging stations, then the charging itself has a lot of loss, energy-wise.

So why not use hydrogen via tanks or fuel cells? We could even keep the engines we have now, with minor modifications, while there is just water vapour leaving the exhaust. Generating hydrogen can be another problem i know..
