In my recent exploration, I discovered that whether a car dealership lets you test drive alone or not can vary. Some dealerships may still allow solo test drives, trusting customers with their cars, while others have shifted towards accompanied test drives for safety and insurance reasons. It's also prevalent for dealers to implement measures like checking your driving license or requiring a salesperson to be present during the drive. So, it's safe to conclude that solo test driving is not entirely extinct, but it's becoming less common due to increased precautions. Always check with the dealership's policies before expecting a solo test drive.
