I don't hate the idea of midichlorians, honestly. Or rather, I do hate them but I think that's the point - to show that the jedi have kind of lost their way, are judging everything by "midichlorian counts" and tried to standardise and automate the process as much as possible rather than properly considering the human element and doing things on a case-by-case basis. If it's not the point then, well... it should be.
I think there are some decent ideas in the prequel trilogy, I just think the execution was pretty bad.
And to prove your point even further: my friends and I went go-karting for someone's stag do a couple of weeks ago and it was £50 per person for two fifteen-minute sessions. And that's even more entry level than autocross, I'd argue!
We had to get there early, too, and get registered, get changed into overalls and helmet, etc. We had to go through an idiot-proof safety briefing. We had to wait for the previous group to finish their session. We had a break between our two sessions for drinks and to cool down / recover, and another session ran during that time, so ~twenty minutes there. All in all, our half-hour of driving probably came with around an hour and a half of downtime, which I think lowers the value proposition even more.
(Plus I got heatstroke during it and got increasingly ill as the day went on - and was unable to really eat during our restaurant meal or drink at the bars later in the day - which lowered the value proposition even more for me, ha!)
£100/hour of actual go-karting, versus £1/hour for most AAA games these days. I don't tend to like AAA games that much, for the most part, but even with all their bloat, recycled content, open-world downtime, etc, they still seem like better value per money per time than anything motorsports-related.
