On the topic of fuel prices and politics of the electorate, did we have "fuel protests" in 2000? As fuel prices rose to high levels, the lorry drivers went on strike and among other effects, nationally the fuel stations ran dry and the economy stalled, I think the Govt political response was a budget measure of price restraint, the fuel duty escalator introduced in 1993 was either suspended or eased to pacify the voter, the easement of the fuel duty escalator seems to be a permanent measure to this day
Yes there were fuel protests pretty much as you describe. Although, mostly it was the impact of people keeping their cars topped up which was a significant issue (in the same way which many new users of EV's have range anxiety when their car is showing less than 100 miles as that's when they would fill up their petrol car).
This meant that people were queuing to access a petrol station, such then lead to more fuel being used due to those queues.
The big difference now is that ICE car travel is no longer so closely aligned to economic benefit.
For example, the impact of such a fuel protest now would be far more muted.
First off, a lot of people who are able to would WFH at least a bit more (companies would be less rule heavy on being in the office).
That's before you factor in the already significant reduction in business travel due to virtual meetings being fairly normal.
5% of car users would be able to carry on as usual (although these are most likely to be above national average in terms of miles travelled, and so it may be that is 5-10% of car miles travelled.
Due to things like the above, it means that there would be far fewer people needing to keep their car above 50%, and so the economic impact would be more limited.
