I do both at home, and ONLY have a CB mobile in the car exactly for that reason.
On 2 meters, it goes out 100 miles Round Trip to some isolated mountain top and to some ham in a city 50 miles from my current location; he has no clue about conditions down the road. Meanwhile I’m stuck in traffic.
Whereas with the CB, you get almost real time data. The guys give you good reports from 5 miles, 2 miles, ¼ mile away from the traffic clog and I can take corrective action, and alternate routes. I find most CB “drivers” to be most helpful.
CB isn’t bad folks.
So when traveling, its CB.
PS: Yes, I operate CW 90% of the time at home – only real hams operate CW and HF you know - but it sure won’t help in a traffic jam!
