I think it's generally wrong to call people posers but people that shouldn't drive jeeps particularly irk me.
Why do you not like people who drive jeeps?
They're usually quite obnoxious.
You shouldn't judge people based on the cars they drive. People who drive jeeps aren't necessarily obnoxious.
Almost every obnoxious I've met was a Jeep driver.
you are being petty and unreasonable here. You shouldn't judge people because of what they drive.
