Electric vehicles- Are we really ready?

Electric Vehicle ⚡️⚡️- A bigger version of a toy car or much more???  A big iPhone with four tyres and sitting space in it or much more?? Are we prepared for these in real life use??
I was born and brought up in a small indian village without electricity, therefore I know very well about the situation and dependency on batteries and its re-charging challenges!
Today when I was playing with my daughter and was forced to changing battery after every 10 minutes, it gave me this thought if we are really far enough with the development of batteries? Have we done all risk calculations? Do we know and have caculated the impact of not having vehicles with the present technology? I am wondering (remembering my Mechanical Engineering’s time) how many years it took for the development of existing technologies. 
I am trying to understand:
  • Do we really know what we are doing? 
  • Are we sure that just banning the vehicles with Internal Combustion Engines in a few streets or countries are going to solve the problems!! ?
  • The earth is round and its impact is also going to be felt all over. Nobody can stop spreading pollution from different streets or countries just by banning ICE engines
  • Did we calculate the dominos effect of destroying the current technologies (job loss or job shift to other countries)?
  • Have we done END to END calculations? I mean not only CO2 calculations for use in vehicles but also in the generation of electricity and all other systems and materials to bring electricity to the vehicles
  • Do we know the lifetime of technologies based on electric use?
Countries with expertise who are dependent on conventional technologies have to think twice before damaging the existing industry and before developing alternative technologies before it is too late. Our future generations surely need a clean and healthy environment but they also need jobs, otherwise they have to migrate for jobs to the countries where environment may not be healthy .
I am not against future or new technologies but I don’t like to destroy the present technology which took nearly more than 100 years, involving many generations and many sacrifices to bring up to today’s quality!
I am here in Germany since 14 years and have many contacts, visiting many functions, meeting many people. During the discussions in such meetings were about the new development in Germany,  but since few months the topic has changed. It is now how many jobs which are going to be abolished in the companies all over Germany. Newspapers are full of job cut topics. Before topics were on investment and now about survival of the German companies by job cuts and thereby creating unemployment and resentment in Germany among young generations.
I am sure all of you are also having such topics around you? So I am just wondering if we are aware with the coming challenges?
ARE WE REALLY FIT FOR THE FUTURE If we ban vehicles with the existing Internal Combustion Engine Technologies (Diesel etc.) and also stop further development of it? Why can’t we keep vehicles with conventional technologies and it’s development ongoing parallel to electrical vehicles and it’s further research?
