First of all they are pushed by regulation both in US and In Europe, you have a certain allowance of CO2 for the whole fleet.
Second thing, for you the price of gas might not be an issue, but for others it is. In Europe where gas is taxed to hell , or even California for example, it matters.
For those doing a lot of city driving, the difference is quite high, I can tell you that in city driving, I have 30 % better fuel economy in the CR-V vs 2023 Outback .
For a while diesel was the solution in Europe, but it also came with high maintenance and low reliability.
Some hybrid technologies are proven over time as very reliable. ( Toyota, Honda ) .
So this why they are pushed to the public. Most of it is regulation, but you still have a choice as a consumer.
