Pre-pandemic, I had multiple employers that were incentivized via the state and county government to push remote working, ride sharing, and transit utilization as a means of reducing overall government spending on roads and road maintenance. It typically showed up as small benefits to the employee, like a monthly drawing for a $50 Target gift card or preferential parking spots. Based on that, I got the sense that while it may have been helpful in the aggregate, it wasn't wildly cost effective.

My state basically did the exact same thing, monthly drawing for gift cards included.
