Anything annoying they stop it as soon as requested. My experience is I have to expressly allow them to turn radio on.
What I don't like: about at least a 15% of rides, the driver tries to take the (very) long way. A couple of times I've demanded them to 'stop me right here'. That's sad for the majority of good drivers out there, but still a problem and forces me to be extra careful, while I'd rather relax and enjoy the landscape.
I've used MyTaxi or Hailo many times in the past few months here in Madrid and have had 0 issues with taxi drivers. I'm not saying there are no taxi drivers like the ones you described above, but I think it's a minority.
I've booked a single taxi journey in Spain, and it was one of the most frightening experiences in my life. The guy was chasing pedestrians and would have run over several of them had they not jumped. He got us to where we were going quickly though.
