My Sister, the rich one married to the Dr needed a driver to a Family do after having eye surgery. First time I ever drove her BMW 4-wheel drive with a Heads-Up display, Fighter Pilot-style speed number projected onto the windscreen in front of the driver. Every time I edged past the limit on the expressway, she told me I was speeding. Couldn't see to drive, but she could see that. Bloody annoying.
