Can confirm with intuitive certainty. For 2 days in Q4 of 2017 here in Bangalore, India, the ride sharing companies (Uber and Ola) were on a strike and those 2 days were the best in terms of traffic (or the lack of it) for us. I'm sure a small segment of the population decided to work-from-home, but since it was bang in the middle of the week, I'm sure most of them availed public transport like buses or used their two wheelers. Of course, some of them used their own cars, but even if they did, it did not reflect in the form of enhanced or even the usual amount of traffic. I've been thinking about this ever since and it feels bittersweet to read this. The validation is good, but the fact that it's actually true to some extent and not just in my head, is sad.
