Re: I'll still be driving myself thanks.

My £5,000 to £1,000 was a poor illustrative example. If the autonomous car does happen, it will probably be made in China by someone you have not heard of, and the cost is of a "normal" vehicle is possibly more likely to be >£10,000 p.a.
I remember the start of a previous major disruption, the mobile phone - Initially only very few people had them, I was working in technology and bought my first one ~25 years ago, now almost everybody has them - The are often rented on a plan at perhaps £300 -£1,000 a year and, whether we like it or not, have radically changed society. The autonomous car (if it happens!) will cause a bigger change.
Your TV room example is poor, initially they were in a shared room (with your family) and many people did rent TVs; now they are so cheap that most of us have more than one, and the young might use their smart phone anyway. The cost of a private bathroom/toilet (which for most of us is shared within the household) is much less. The shared kitchen is becoming a reality for the urban young because they are starting to use their mobile phones to order meals from "dark kitchens" and many do not cook for themselves (I don't count a microwavable meal as cooking) - Another, perhaps, unforeseen product of the disruption caused by mobile phones. I know several young urban dwellers who don't have a car, and use Uber, again another disruption caused by the phone...
I did not say I liked the idea of the autonomous car, but if we survive the next 20 years (I won't be around then), it is inevitable - Moores Law generally applies to almost all technology.
