Depends on you definition of "worse", for me the consistently most annoying are Toyota Camry drivers, especially the white and silver ones. They drive 10km's under the speed limit, in the right hand lane, have at least one brake light that doesn't work, don't use blinkers, do 60 kph when merging into a 100 kph freeway and slow down half a kilometre before they want to turn. The non silver and white Camry drivers are tail gaters, sit 2" from your rear bumper, push in if you leave half a car length space to the car in front, accelerate when you try and pass them and block the shit out of you when merging. Not a day goes by where I don't see a Camry driver doing one or all of the above.
