Driving in Houston?

Hi everyone, I might be visiting Houston and would most likely have to rent a car I’m assuming. However I’ve heard the driving is stressful there and I’m looking for some insight. I have driven in NYC, in LA and in Pennsylvania. I’m mostly wondering about aggressive driving. NYC is very aggressive, lots of honking, people not allowing you to merge etc. Is it like that in Houston, or is it mostly just people speeding but minding their business? Thanks
