Statement: Cities that invest in public transportation see a decrease in traffic congestion. Statement: Riverside has not invested in public transportation. What can be properly inferred?

Self-selection bias means current remote workers chose that arrangement, so forcing it on everyone may not yield the same satisfaction levels.
