So first of all - France is known for it's remarkable protest culture. That's not typical. Secondly, the fuel tax in question, while reasonable and necessary, is also a somewhat special case even in France because it represents taking away peoples everyday mobility. As cars electrify, that will be less so, and other measures - such as those targeting luxury travel like air travel - would surely not see quite the same levels of protest. And at this point, because the protests were widespread, and because they succeeded, there is going to be vigilance against sneaky plans by the government to pass it while nobody is watching - but that too is a fairly local issue.

I expect that even in France those tax hikes will eventually pass, even if it takes longer than elsewhere and much longer than other measures. It may need some other compromise, like a comparable tax-reduction for median incomes; and some level of political maneuvering to placate the particularly hard hit. Or perhaps they'll try to achieve similar reductions via other measures such as speed limits and regulations on cars. But I don't think it's representative of social upheaval vs. climate-change cost in general, anyhow.
