Porsche, BMW, Merc, Audi all can - maybe relucantly but if that's what it takes to sell a car it will happen with the right dealers.
Some might limit that to a few hours or put restrictions around it, but I've never experienced anything quite like the Emira test drive. As an example BMW gave me the keys to a car and asked me to be back by 4pm the next day. Porsche were less flexible and instead gave me the keys and I followed the salesman on a lovely cross country test route (he was in a Taycan S and not holding back) - they then invited my back to try the other model I was considering either for an afternoon or to do the same depending what I wanted.
To drive the Emira I turned up to the Hyundai dealer, went into the small Lotus side building and waited for 10 minutes for someone to appear. Did paperwork, they drove the car for the first few minutes and we swapped. The route was crap, 30-40 mph limits through towns and villages with a few miles of slabby concrete national speed limit A road near the end. Salesman (if they are called that now) was perfectly nice but he didn't have much info and it felt simply like he was there as a chaperone.
I'm not one for coffee with the Audi logo in chocolate dusting on the top, but a warm showroom where you get offered a drink is nice, and the opportunity to really drive the car is essential.
