Footwell Icemaker
A lot of the cars you see today have built-in coolers and ice makers. This is a feature that originated in the 1980s. Footwell Icemakers was a way that automakers incorporated more homelike features into conversion vans at the time. The Toyota Van was the first vehicle that sold a mainstream footwell ice maker until the feature went extinct. The premise was simple and most drivers who owned these features appreciated having it built into the van (via Car & Driver).
Later on, cars like the Pontiac Aztec tried to experiment with built-in coolers and such. But it was the modern era that brought automotive refrigeration into the mainstream. Now you’ll find one in just about every high-end car vehicle like the Jeep Grand Wagoneer.
