I suppose the upside of flying cars is that it will get some [censored] off the road. The downside is that it will put them in the air!
Safer cars promise us: "Rounder and softer vehicles will appear as safety laws shape vehicle design. They will have sensors to detect pedestrians and other cars and will have air cushions inside and out." So peds and other cars will be okay but it looks like us cyclists will be in danger for a while longer. Must be a technology thing.
I wouldn't mind be able to combine bicycles and jetpacks, it'd give one more side to pass queuing cars on.
