Internationally the statistics depend quite a bit on how the data is collected and aggregated, so do it's hard to international comparisons accurately.

I will say using US definitions, commute times are very sticky around the 30 minute time period. Longer commutes and people have a large incentive to move closer, short ones and they don't generally bother.

So in the US Tulusa Oklahoma population 400,000 (1M metro) has a 20 minute commute and NYC population 8,800,000 (20M metro) is 50% worse at 32 minutes average and ~100 cities between those extremes. https://www.titlemax.com/discovery-center/planes-trains-and-...

Edit: This suggests allowing people to move easily move around the metro area would meaningfully lower the need for transportation infrastructure. I suspect NYC has issues with people living in rent controlled apartments having long commutes but being unwilling to leave their cheap apartment, but don't have data backing it up.
