"the benefits of 5G in transportation and health"
Which are what, exactly?
Video doctor's appointments can be done over fixed broadband connections. Video over 4G works in the few cases you might need it (e.g. at the scene of an accident).
And self-driving vehicles had better be autonomous if you don't want them to crash into each other. We can't even get 3G/4G to cover 100% of the road network - so what chance 5G where you need cells every few hundred metres? What happens when your self-driving car needs to drive into a valley, or down a country lane?
