I know this is not an answer to your question, but I’ve found everything to be immensely easier with a second drive. I’ve screwed my pooch before!

Not my favourite map. The vortex transitions were a bit janky, and would spit out out a weird angle or not work at all on occasion. The drifts are the start were also very awkward, likely because they were inspired by the real circuit. Cool idea in theory, but it didn’t end up being super fun to drive.

Good luck! 21 took me just under 7 hours according to grinding stats. It was the toughest grind I’ve done before.

I’ve been playing for a similar amount of time. I started in November, though the spring season I hardly played.
