Yes.
Lots of gesticulation, occasional shouting.
The worst?
I used to thank people who waited at side roads by nodding & saying "Thank You".
I did this one day and the guy in the car chased after me, drove alongside shouting "WHAT DID YOU SAY TO ME?" over and over, then swerved in front, got out of his car and squared up to me. There was a lot of posturing, and he drew his fist back as though to punch me (although he didn't). He lip read my thanks as "F*CK You" and wouldn't believe that that wasn't what I'd said.
On my commute though, the larger danger is indifference and inattention. I gave up counting the number of people driving whilst talking on handheld mobile phones a long time ago.
Here's the thing about riding a bike in Britain. No one in authority gives a shite about you. The government make big noises about promoting cycling, and most of the political parties who want your X in their box will do so too. But when it comes to actually making a difference to the way you are treated, they aren't interested. Both times I was knocked off due to driver inattention, the police did precisely f*ck all, despite the drivers in question being unable to see 6'2" of man dressed in bright yellow with 5 lights on the go. It's just one of thiose things to them, you see. Both drivers are still out on the road, and nothing has happened officially to revise their attitudes, or retrain them.
Hunter S. Thompson wrote that the only thing keeping drivers in line was the threat of legal or physical consequences for their actions. Both are vastly less likely and severe if they choose to take their frustration out on you, rather than another motor vehicle or the street furniture. We are a country that can trumpet about it's road safety record whilst ignoring the fact that we do incredibly poorly when it comes to the safety of people not in cars. We are a country where supposedly rational people can laugh at "jokes" about driving into cyclists deliberately, and make the assertion that strict liability would result in cyclists throwing themselves under cars deliberately. Where thuggery that would see you up before the judge in any other circumstance is just "a bit of road rage".
Which isn't to say that it's not possible to ride a bike here and have fun doing so - that happens pretty much every day for me, and most people are ok, and rides aren't frustrating as long as I expect fellow road users to be distracted and indifferent to my safety.
On balance, I think the positives to riding a bike outweigh the negatives, but keep your wits about you and be VERY wary of escalating things with drivers.
