Here is another study from the UK... not sure I believe that 40% will stick with the program.

UK drivers are ready to reduce their driving to maintain clean air as a result of lockdown; Portugal is rolling out a €7 billion green hydrogen strategy.electrek.co
UK drivers: a big change coming?
The AA took a poll of 20,000 UK drivers, reports the BBC, and 40% said they would drive less in order to maintain the clean air that has resulted from the pandemic lockdown.
Further, 50% said they would walk more, and 80% said they intend to take some action to reduce their own adverse impact on air quality.
Further, 25% of drivers said they planned to work from home more, 25% said they would be flying less, and 20% plan to cycle more.
Survey shows most people will say what the survey wants them to say. The rest say the same but option b on the questionaire.
