That's not really comparable at all. A color tv is a fundamentally more distinct product as compared to a b&w tv than a ICE cars is compared to an electric. Especially for the foreseeable future.
Because a colour TV is fundamentally and objectively better at its primary use case (watching TV). A petrol powered car will get you from A to B just like an electric one.
Range lower, maintenance costs higher. The argument goes both ways but whichever side you are on, we are on the same side that EV are fundamentally different than gas cars, at least as much as color TV vs b&w.
In my mind, just as getting 3x more colors gives you exponentially richer storytelling, 3x more range (way more than that actually, since a gas car can be in almost continuous use with brief stops for fuel) gives you the freedom to go exponentially many more places, do things etc
Oh don't get me wrong - there are advantages of course. But people are underinformed / bad at calculating whole of life costs / don't have the extra cash available so a cheap petrol vehicle will look appealing. There isn't the "wow" factor of comparing colour vs B&W TV - especially at the low end. The Nissan Leaf was a nice car to drive but it wasn't impressing anyone because of how cool it looked.
Because the primary function of a TV is displaying moving pictures while the primary function of a car is not related to its fuel type. The general public has not yet shown a dramatic interest in electric over ICE, but improvements to TV picture have been shown to be major drivers of adoption from color, HD, 4k, and so on. That is the whole reason why these laws are being considered, to help move people off ICE cars quicker than they would in a normal market.
