You may laugh, but that is how adoption curves work. When color TVs were first introduced, no one wanted one. They were big, expensive, and there weren't many shows broadcast in color. Then the prices came down, color broadcasts went up, and within a couple if years color TVs were the norm. Nearly identical adoption of HDTV.
America and South Korea have been slow to adopt EVs. In most countries, EVs went from 5% of new car sales to 15% in under 3 years. We are taking closer to 4 years. But we will reach a mass adoption point where sales will accelerate rapidly.
I agree that 2030 could be overly optimistic to achieve 50% of new car sales, unless we get solid state batteries with over 600 mile ranges. But 2032 seems almost certain.
By 2035, our options for new ICE vehicles will probably be severely limited.
Have you ever been to other countries? In many countries, especially those in Europe and Asia, people don't drive like us. I have a buddy (AF EOD) who married a german gal, he said everything her family does is in the village, they eat the food in their village and drink the beer produced in their village. They may have family members 20 miles away and rarely travel to see them. Plus they have trains for short and long distances (which is an awesome way to travel). Many middle class don't even own vehicles.
Even it they stopped selling ICE vehicles in 2028, when Supreme Leader Elon takes over, we still wouldn't have 50% EVs on the road in the US by 2035.
EVs have their place and role, but they are not a good fit for many of us in flyover country. The much ballyhooed 300 mile range is really more like 200 or even less - if you are running the AC, towing, taking on hills and mountains. etc.
In 2021, $7.5bil was allocated by congress to build EV charging stations across the country, as of May 2024 a grand total of 8 are up and running. I don't think many understand the infrastructure required.
