Sort of. While electric cars are great, the type of person who buys a $3,000 car cannot afford the cheapest electric car for about 10-15 years after that tipping point, even after you account for gas savings. So new cars are likely to switch suddenly, it still will be a decade before that catches up. The average car in the US is 12 years old.
Even the type of person who buys a 3 year old car cannot (will not?) afford a payments on a new car accounting for the gas savings. They will buy what they can get - but they also will influence the market as they are likely to be sensible (often a new car is not sensible) and so willing to pay extra for the EV, and this in turn will put pressure on the new cars since trade in value is very important to most people who buy a new car (which is sensible, but it is the banks forcing this on the buyers)
