The major benefits of 5G has nothing to do with cell phones. The applications of 5G to other devices including connected cars and industrial campuses is going to be huge and you'll see accelerated infrastructure builds in densely populated areas (faster than LTE) - because that's where you get the benefits. There isn't much benefit in sparsely populated areas. It's about having single digit millisecond latency for 2 way communications between devices and between a device and an application.
Around here it seems to be Subaru Forrester and Outback drivers who like to go too slow on the backroads.
Some things I notice... almost all Toyota and Lexus drivers will not use their headlights, no matter how foggy or rainy it is.
All Prius drivers who do use them, always have one headlight burned out.
Most Hyundai drivers have at least one bad brake light
Tesla drivers do not know what turn signals are.
Acura drivers cannot stay in their lanes going around even the slightest of curves
My issue with electrification and AV is the order of magnitude the "experts" (Big Jim's hero Tony Seba) have predicted.
At least in the US, I don't think we will see more than about 25% market penetration for light duty vehicle sales before 2030.
MUCH TOO EARLY to say it is "correct" !
5G won't be available wide spread for more than 5 years and in some locations (graphically large, but low population density) it might be well over 20 years, IF EVER. (Look at a 4G map. Lots of "white space, even today.) My gut says, 5G will be a niche, but people will pay the premium for it because it is "cool".
Despite Hackett's rhetoric, he knows "which side his bread is buttered on". Major investments in SUV/CUV, with or without hybrid, look like they will pay off. This is imperative if he want to see electrification an AV actually get to production. Wall Street still has not "rewarded" him/the company. Long term investors won't buy the stock (which is at a close to a 10 year low) because they fear the dividend will be cut (as it has several times in my lifetime).
