Sprint events are a godsend for knocking out those accolades. Also if you pick one of the DLC bikes and city tracks you're almost guaranteed a top 10 spot in the leaderboards

One of them (Yamaha at Port Vancouver) doesn't even have any time set yet! Easiest top 1 WW record ever
This prompted me to count how many individual leaderboards there are in the game:
We have 134 vehicles (cars + bikes) and 114 tracks (19 for each 6 locales).
Then we have 3 event types (TT, Sprint and Drift/Skill). I don't think Race has a leaderboard but correct me if I'm wrong.
Then dry/rain has their own separate leaderboards.
So in total, 134 x 114 x 3 x 2 = a mind boggling 91,656 possible combinations
To put that into perspective, let's say it takes you 3 minutes average to do one combo (including loading screens, and accounting that some events are shorter/longer than others), it will take you 4,583 hours to try them all, or just over 190 days, or just over 6.3 months of non stop playing
Or another perspective, if Driveclub has GT Sport style daily events with 3 events rotating each day (not weekly), then it will take 83.7 years before each combo is exhausted
And that's just leaderboard events. If you add in possible combos with different time of day, dynamic time/weather, AI number/car type/difficulty then the numbers are going to get much, much bigger
Small wonder there's always something new to do in this game and you never get bored
