Even in the USA, the number of gas stations has been declining for 50 years. They've gotten more pumps at less locations. Cars don't break down anywhere near as much as 50 years ago, which is why most fueling stations don't have garages any more.
In a lot of areas even in the USA, gas stations have a started having trouble getting loans for more than a few years.
Just like in California becuse 25% of new cars and 5% of total cars are BEV now and the rest super efficient, they've got refineries shutting down because gasoline usage peaked in CA a decade ago, and it's expected to continue to decrease. They made most of their money from gasoline. They can't afford to make the necessary upgrades and repairs, when their main product is decreasing over time. In the past it didn't matter if they expected a decade at current rates to payoff, because they knew usage had to increase over time.
Gasoline and diesel have only stayed so cheap because they've had large and continous growth. Natural resources only stay the same cost if your pulling at a low enough rate, or your either finding new cheap supplies or developing tech that makes it cheaper. The rate of finding new oil deposits has plummeted, especially related to the cost of searching. Same with developing tech to get/refine oil cheaper, we've been getting more and more diminishing returns.
We are within a few years of peak oil. The USA peaked gasoline already. As refineries, gas stations, and the support stuff start needing expensive maintenance/repairs/replacements, they are going to decide they can't afford it. The companies that make fuel pumps are going to start closing, lowering output, and increasing prices, the companies that do the inspections of the stations are going to have a hard time finding employees so it's going to cost more and take longer for gas stations to be inspected. Fuel truck companies aren't going to be replacing trucks, they are going to charge more and take longer.
Gasoline, the parts, and the people, will start getting more and more expensive and harder to find. It will seem like nothing at first, but then start happening relatively quickly. It's a feedback loop. As prices go up and access gets harder, people switch to BEV faster, which causes prices to go up and stations to close.
This has happened with other industries in the past. Batteries are on track to be cheap enough within a year, that BE cars have a lower upfront cost than ICE cars. It's already happened in China that BE cars are cheaper upfront.
