Updating this study with more recent data including 2022 would make the results much more valuable and meaningful. I suspect that the trend would continue and private automobile use would continue to decline. I think there are multiple factors contributing to the trend, two of them being cost of fuel rising and purchase price of vehicles rising. In some parts of the country, more public mass transit has become available and rideshare services grew in popularity. Working from home certainly cuts down on private vehicle usage as well.
