Petrol and diesel cars really ought to be phased out as soon as possible - the environmental factors are considerable.
I do not really miss the smell of petrol or diesel - did I ever sniff it in while down at the pump? [Glue sniffers anonymous watch out!]. Given the rate of progress, I can see a sensible transition to alternative motive power via plug-in hybrids, though that would depend on how they actually work.
One thing I don't know about the plug-in hybrids is whether they work totally on electric power for (say) 30 miles, or whether they work with a power combined from the ICE and the batteries. Also, if working on ICE, do those also generate spare power to charge the battery for (say) 30 miles?
For example: one scenario for a plug-in hybrid.
1. First 30 miles - EV only. 2. Next 50 miles petrol only. 3. Next 150 miles petrol, but also recharge the batteries up to a 30 mile capacity. 4a. Next 50 miles - petrol only but no battery charging OR 4b. Next 30 miles battery only followed by the final 20 miles on petrol only.
A scenario like that would have advantages for long range travel in regions where charging was sparse or unreliable. In the example above, at step 4 - the user might be given a choice depending on whether charging points were available at the destination or not. If they were then, it would be better environmentally to have an almost empty battery at the destination with no ICE use, but that might increase risks depending on whether petrol/diesel or charging points were available at or near the destination.
I am still unsure about the possible role of hydrogen as a fuel for cars. Environmentally it's damaging if it's not produced in a sustainable way, and there are hardly any hydrogen based cars available. However if hydrogen is available, then I believe that recharging might be easier than electric charging. Also note that the more powerful EVs have considerably more power than most other cars, including many petrol cars - though in the limit petrol heads who like power and burning fossil fuel can still produce and use cars with more power than EVs.
