You can sort overtake by most downloaded, top reviewed etc. I think most of us here have at spent at least an evening or two going through that list

. Upload & last updated date may give you a little hit as to whether the car may have "new" CSP goodies (Extended phsyics etc). Plenty of good cars that are a few years old+, but just something to look at when browsing imho
Of course everyone has their own preferences and likes when it comes to tracks, but if you want somewhere to "start" with, this is a small list of modders whos tracks (mostly race tracks) I drive a lot and can usually expect a quality "product". Most of them have at least 3-5 tracks if not 10+ I apologize in advance if miscatorgirized anyone on it.

Another great resource I used along the way was
GutBomb's Multiple Track Review list (I think this is the "most recent" version). For many tracks that have multiple versions this gives you a run down on what each brings to the table. Not all encompassing for some newer tracks, but super helpful nonetheless.
As far as screen recording goes, I use the built in windows recording with the win+alt+R keyboard shortcut. But it's more for shorter clips, haven't done long recordings on it.
