It's 300,000,000 downloads, not 3,000,000. That isn't even individual users as many people, including myself, have downloaded the application more than once. I'm also not clear how that works with updates.

Given the Formula E files were given away for free with big discounts for updates then I would assume that 400K concurrent players is a good indication of the number of current players.

The WTTT regularly attracts 200K players a week so I would suggest this is a minimum number. However, you need a reasonable garage before you can run all four stages every week to get any reward. So a guestimate somewhere between 200K and 500K regular players is not a bad guess.
