Buying a car in the age of AI

One thing I'm not great at is buying cars. I'm incredibly indecisive, in part because historically I have regretted some of the cars I've purchased. Hence, I'm afraid of buying the wrong car, and so I vacillate endlessly to an almost neurotic degree. Also, buying cars is tough because you have a limited number of test drives — test drives require visits to dealerships and lots, and you don't have unlimited time and patience at these places.
