The logistics and retail part of fuel (post refinery) are not particularly high margin. I suspect this means it would be quicker than people may think for petrol stations to not vanish but thin out significantly. This would lead to price rises, I've not ordered bulk fuel for retail but have in the past for commercial use and the price difference on ordering 33000 litres a week is tangible compared to 16000. The retailers will see margins shrink and will need to make up for it by passing the cost on, the little independent places just won't survive.

Using my estate as a "straw poll", so by no means accurate but still illustrative. Most of the cars here 66%+ are 10 years old at most, now most new and first time used sales these days are on some form of PCP type plan. These "rental" type plans mean the initial buyer and the 2nd buyer don't care much on the ticket price, just the monthly. That renders alot of the "cost" of the EV moot. So if we say from 2030 onward (lets ignore earlier sales) all these new cars are electric, 3-4 years after that those enter the "approved used" market. Within a decade that is the majority of my estate in electric cars. Extrapolate that across all of Tidworth and I'd bet our Petrol station is closed down before 2040. That then pushes me to just outside Faberstown to fuel up, though that is a small independent so probably shorter lifespan than Tidworth, leaving me with a 20 mile round trip to fuel the car. At this point I say "balls to that" and buy a used EV.

I think bikes are different, most are toys and passions. If I'm going out for a ride on a nice day the extra mileage for fuel wouldn't bother me, neither would price rises. I can't see fossil fuel totally vanishing, agriculture, commercial and plant will need diesel for a significantly longer time than private vehicles and (I stand to be corrected) if you are refining diesel you are also making petrol.

Obviously all of my above thoughts are based on the assumption that the current issues around charging, power supply and the like are dealt with by our Government (I struggle to type that with a straight face).

and you never know, maybe in a decade electric bikes are so awesome we are all clamoring to get one!
