@xgranade okay so here's some informed speculation then:
1. as others have said; it's more highly visible than other prices
2. energy prices affect the prices for pretty much everything, and gas prices are a strong proxy for that
3. fluctuations in gas prices are rapid, allowing people to react to them before acclimatizing
4. longer-term solutions to this problem are *very* longer-term (building a rail line in the US takes like a decade)
5. cultural memory of rationing in the oil shock of 1978
