Yes, gas cars would disappear very quickly at that rate of carbon taxation.

"People in general" would absolutely use non-planet-ruining versions of basically anything, the problem is getting there -- most people do not even think about the polluting effects of every item they buy, and could not even if they wanted to given supply chain complexity.

Unfortunately these decisions are made for them, largely by the realities of economics and policy: when you have the option to pay to internalize the external cost of travel yourself, most people don't -- why would they? No one wants to act alone to hold that bag, that's literally one of the main reasons for policy: to engage in group action for group advantage where individual action is a competitive disadvantage.

Redistributive taxes on carbon emissions are likely something many people would support -- were it not for concerted efforts to the contrary by individuals and industries that stand to lose stature as a result. But on carbon capture: there will absolutely continue to be near- and medium-term use cases where burning petroleum products and then capturing the CO2 later is the most cost-effective approach. (Or vice versa, via synfuels.) There will still be a carbon cycle, and we will still want to have many levers on it.
