It has meant no test drives in practice. I was shocked when I tried to test drive a Ford Mach-E that no dealership within a 100 mile radius had any inventory on hand -- when I called individual dealerships to ask, they said not only was the entire inventory already promised to individual customers and the only way you could test drive was if someone bailed on their order. I got a few emails that inventory had popped up, by the time I called (even within a few hours!) the vehicle had already sold. I'm genuinely shocked that consumers are buying first production run vehicles entirely online without a test drive.
