We believe in the EV technology of Tesla Motors (surely in combination with the Superchargers).
Anyway, I doubt it that there will ever be (in this century) a situation that we will have 100% EV's on the roads, and no ICE vehicles at all (0%).
The highest % of EV's on the roads will be 99%, in my opinion.
My prediction on the development of the total number of EV's on the roads is:
2020 - 10%
2030 - 20%
2040 - 40%
2050 - 60%
2060 - 80%
2070 - 90%
2080 - 95%
2090 - 97%
2100 - 99%
The last part will be hardest to gain.
Does anyone have any thoughts on this?
