My offroad club uses UV-5R radios (and other Baofengs) exclusively...we have for quite a few years. One of our club members programmed them to have the legal non-Ham channels - I believe they are GMRS? or FRS? I don't recall but it was researched extensively and what we are using does not require a license. Other frequencies on the old UV-5Rs do require a license.
Speaking from about 15 years of experience with these things - they work about as well as CB, maybe a little better. If you are in a canyon or hilly country they may only have a usable range of a couple hundred yards. Line of sight might be a mile or two in the very best conditions. External antennas mounted on your vehicle help... that defeats the purpose of a handheld though... if you have two handhelds with stock antennas being used inside vehicles, the range is not good. Half a mile or so maybe.
There are also some significant quality issues. I'm guessing 25% or more of the radios we got quit working at some point. Some won't transmit, won't receive, or both. Pretty high failure rate but not surprising, I think we were paying like $12 per radio back in the day and they are only $18 now.
I have a Juentai 25w dual band stationary radio in my Explorer and I am super pleased with it - I have a pretty nice antenna and both the transmit & receive range is excellent. I'm guessing 10-15 miles at least, maybe more. You can't get this radio anymore though.
If I was starting from scratch I would be looking at Midland GMRS radios... great quality and legal to use.
