I bought a handheld CB for my van back in the early 80's and have carried it since. At the time, I bought it in case I had to ask for some kind of help from passing traffic (breakdown, medical emergency, etc) and used it for traffic info--- mostly how long the backup I was in was going to last. I still have the CB in reach but very seldom turn it on. And I don't bother moving it to the truck when I'm taking that instead of the van.
Now we have cell phones and an Inreach for contacting emergency services and we have online apps for traffic backups. (We also carry a pair of FRS radios).
We started using Waze on the iPad for traffic backups a few trips back and really liked it at the time. Then an update came out and seemed to cripple it. Maybe I just didn't play with it enough to figure it out but I could no longer 'see' down the road far enough ahead to suit me.
I then happened upon the Show Traffic function in Apple Maps and liked it better--- quicker startup, familiar interface, fewer orientation and zoom-out/zoom-in problems.
I don't feel confident enough to actually say Apple Maps is better than Waze; it just seemed easier to use. I'd be interested to read other perspectives on Waze and the traffic functions of Apple Maps and Google Maps for IOS.
