Several Times I Thought I Was Going to Get Hit

This started on westbound Interstate 64 (40/61 to us older folks) near the entrance ramp for Lake St. Louis Blvd. The Ford driver accelerated to change lanes right as traffic in my lane slowed and I thought for sure the driver was going to hit me, but fortunately they did not. Love the fact they threw their arms up in the air like I stopped just to upset them.
This poor driving continued onto the westbound I-70 entrance ramp and onto I-70. They were still driving poorly when I lost site of them when they took the Foristell exit.
This is the first video I have had to compile from several clips from my dashcam. Shotcut was used and it was somewhat of a challenge to get the individual clips sped up in places, normal speed in others and then sped back up and then compiled together. Mainly because I had no idea what I was doing. Hopefully, it will get easier in the future.
