Not keeping proper distance to the vehicle in front or behind them

Accelerate, brake, accelerate, brake, accelerate, brake on repeat when on a wide open road.

Some drivers do this seemingly without being aware and once you notice it's impossible to ignore how irritating the feeling is.

People who know damn well they have a right turn coming up in fewer than 30 seconds, but are perfectly comfortable riding that left lane until the last possible second before they violently swoop cut across all lanes of traffic at once to make their turn.

Bonus points if that turning lane is swamped with other cars, but their tunnel vision was so deep they don't notice until they attempt to merge, and they become frustrated that they either can't make it, or they have to aggressively steal the right-of-way to force themselves in.

My father in law brakes incredibly late. Consequently, he brakes very hard. Drives me (heh) insane, and causes me to reach for the oh-shit bar and the ghost brake every time.

My wife will not turn off her wipers even when it's no longer raining. Drives me mad.

This is a weird one, but a personal pet peeve. Assuming no one is behind you and there are already some cars at a red light ahead of you, there is no reason to accelerate. Let off the gas. Coast. Sometimes the light turns green by the time your there. If you keep accelerating and stop that's just wasted gas.

Yelling at the other cars the whole trip...

Getting on a cell phone.

My former boss's wife used to steer very strangely when driving - The Jeep was likely out of alignment, but instead of staying centered and making continuous small corrections, she'd let it drift to one side till it was on the line then quickly correct back towards center and then continue drifting, endlessly until arriving at the destination.

My brother once drove 60mph down a winding narrow mountain road one-handed while sipping tea. Cool story to tell now that i say it like that, but i can assure you it was not cool to be in the passenger seat at the time

You wouldn't want to ride with me, then.
I generally don't secure the seatbelt until I'm moving forward. Not sure why, but I've always done it.

I'll mess with the rearview mirror often, as my position in the seat may shift, and I can't stand it when the view in the mirror isn't centered.

As for the radio... I channel surf like mad. 40 presets and I'll scan through them all before deciding on something that I never stay on very long. My wife can, not, stand it. lol But, the radio controls are on the steering wheel, so doing so isn't a distraction.

In the past, when I drove any of my vehicles that had a manual transmission, I had a habit of rattling the gearshift at stoplights. People who rode with me didn't like that either.

People that want to be pals on the highway. Get the fuck away from me!
