This reminds me of a fun little experience on a production shoot. The producer had hired a company that specializes in recording the sound of a car. This wasn't just the sounds of the engine running or driving, but the sounds of the car handle from outside and inside, the sound of the door opening/closing again inside/outside. Apply this to every aspect of the car. Pedals, shifters, ignition switches/buttons, trunks, and on and on. Basically, a sound designer's wet dream. This shoot was not meant to have any dialog delivered, it was all about the car, so these were the only sound team available. When a typical snafu with scheduling was announced, we needed to get a quick sound bite from an actor but gear was unavailable. When the producer asked the car company to help out, they were aghast at the gall to even ask them to demean themselves. Ultimately, it was recorded with an iPhone voice memo.

The final mix of the car was amazing though
