Auto industry development cycles are minimum of 6 years so no way are we going to see the end of the gas engine any time soon
Doubt we will ever see complete phase out of combustion engine.
We will see very well integrated hybrids that use regenerative braking and a very efficient small internal combustion engine to keep the battery charged
Very high performance, energy efficiency and smaller battery volume
“Doubt we will ever see complete phase out of combustion engine.”
Likewise for typewriters, film cameras, wired telephones, etc.
...oh, wait, um...
Those all died while I worked at Smith Corona, Kodak, Nortel, etc.
