I notice they only ever show the roads with a few cars on them. No traffic jams with irate people hurling abuse at each other. Noone cutting you up in a 4X4.
A nuclear tunneler- that'll be the day, you wouldn't need to install lighting, tunnel walls would glow in the dark, and so would you after a trip through it!
They seemed to think nuclear energy was going to solve all our problems back in atomic era.
Still, some things came true. Radar on cars, little tv screens instead of rear view mirrors, safety devices, traffic bulletins (which tend to warn you about 30 seconds before you actually run into the jam!).
Air ambulance is also a reality. Conferences held via screens.
What they didn't predict, is that with all that ease of living, so many people would end up as large as the houses they predicted they'd live in.
