Discription of Events: On double lane highway as I was passing in the left lane, van began swerving over the line intentionally into my lane (did this twice) because he didn't want a Jeep Wrangler passing him and wanted to be ahead so just shove me out of the lane rather than use a directional. Because I stood my ground and didn't end up being driven into oncoming traffic I got the finger and obscene gestures from both the driver and passenger as they tailgated behind me. Not sure what the hate is towards my vehicle is all about but these guys were oozing ...and potential to be criminals of vehicular manslaughter. They need to be watched!
