People sure do drive aggressive. It's been getting worse for the last few years, but it's reached a point where it legitimately feels like you're engaging in battle when you drive.
Everything's a competition. All "me me me" with people diving up inside lanes to push a car length ahead, and doing that annoying bunching up so they don't have to let someone in who's merging.
Just weird behaviour in general. If driving is so stressful, catch public transport.
