Thanks metoxys!
To finish in a year (if people stopped posting any more tracks from now on) I'd have to drive about 40 tracks per day.
So, what I've decided to do is this:
I will try to post videos of at least 50 tracks per day. But I will not restrict them to only my own replays. From now on I will take whatever replay is the best posted and make a video of that. This should give people even more incentive to post the best times. It could be a video of your run that gets made.
I'm also still doing the project to drive every track myself, but this will alleviate some pressure on me to set crazy good times on every map.
