In-car entertainment

I reckon manufacturers’ failings have created some niche opportunities for design entrepreneurs. Why has no one produced seat belts for dogs? Worldwide, there are millions of people who drive around with a canine in the boot. I’ve seen footage of a dog flying from the back of a car and out through the windscreen via the unprotected head of the driver; it must have taken them hours to clear that lot up. There’s also a whole host of items that British drivers might like to use while driving abroad. In France a sign on the back of your car saying: “Oi, stop tailgating me you French lunatic” might be useful, for example.
