I discovered some innovation that I was otherwise unaware of yesterday. I know modern vehicle keys are pretty advanced in terms of security and I already knew our BMW keys charged their battery whilst in the ignition and stored audio and climate control perferences etc. I'm also sure (MB too no doubt) keys have stored memory seat positions too for some time and I expect many manufacturers have some variation of this. But the use of technology that while I suppose is quite simple really with today's potential, was one that I thought brought a simple and worthwhile convenience to customer service. Sat in front of the BMW service desk in the dealership, I am asked for my key. When presented it was slotted into a device connected to the computer. Up pops the cars details, including miles to service etc etc. I am told newer models include detail such as if the seat belt has been worn, if the fuel is down to the reserve or not and fault codes if they have been thrown. No more forgetting your registration, not knowing how many miles are on the clock, miles to service etc. The service receptionist even knows the fault codes before the car enters the workshop! It was a practical application of technology that struck me as pretty neat.
