Yes it will certainly make an impact over the next few years if the car makers ramp up EV production at a reasonable price.
I have a feeling the old, entrenched Western car makers may drag the chain on EVs by not making enough of them and charging too much for them. It's worked in the past.
Elon Musk is well aware of this at Tesla and has deliberately tried to subvert that strategy with his promised Model 3.
In response, we are seeing a growing number of "analysts" trashing Tesla stock, trying to limit or undermine confidence in the company and its plan in order to make it struggle financially. They may be successful.
But even if they are.....there is China. China is going crazy developing and making EVs. They are improving rapidly. They don't give a rat's 'Rse' about western financial analysts allied with vested interests in the oil and auto industries.
If Tesla falls over through dirty tricks....there will still be a dozen Chinese EV makers (currently almost 200) happy to sell us their cars. Cheap.
