How much more would gas prices need to rise for people to start taking public transportation (Elasticity, Supply and Demand)

This is a very difficult question to answer as it will depend on the region and access to adequate public transport, population of said region, disposable income after essentials like food/power/etc per capita of said region, WFH policies, average commute miles per capita, average leisure driving miles per capita, inflationary impact of said region, etc.

For many across the US, there is no true public transportation alternative. For example, in Texas there are many cities where a 18-20 drive to work easily becomes 1.5 hours (one way!) along with a 10 minute walk if you try and take the bus, making public transportation a non-starter for most. 

And if more people move over to said public transport, the system may not be set up for such a surge and wait times could increase significantly, pushing people back to cars.
