This depends on how you define ROI. Car infrastructure and lack of density reduces tax revenue for cities and strains infrastructure.
There are other human benefits to reducing car traffic and use in favor of public transportation: * Reduces air pollution * Noise pollution * Allows a focus on human centric urban planning * Allows for higher density commercial and residential increasing tax revenue * Reduces pedestrian traffic injury

Climate town videos are all well researched and provide an enormous amount of follow-up content from their sources.
Generally, I care about all of the above and I perceive investments in public transportation to have a higher ROI.
Some extra historical context is helpful too: https://youtu.be/oOttvpjJvAo?si=ZGXF81qJnD_Fgw0L
The book The Color of Law by Rothstein is worth a read.
In the end there is a balance between public transportation and car dependency and right now the scales are leaning too much in favor of cars.
Thanks for this useful comment, too rare in this discussion unfortunately.
One thing to bear in mind is that roads are required no matter what, so the question is one of size, really. In general public transport shines and is definitely worthwhile in dense urban environments where cars-only infrastructure could not cope or would be completely disproportionate. As density drops usefulness and viability drop, too.

Not sure that is the case in Europe. In Europe this tends to be driven by militant groups that want to ban cars for dogmatic reasons and they create real problems for people and businesses in the process.
A pragmatic approach is indeed to have a good balance and to accept that cars are both wanted and useful, and needed in many cases.
