Oncoming Ambulance. Driver in front of me and I both deciding whether it was safe to move to the right in case the ambulance needed to come to our side of the road. I start to move to the right - not even halfway out of my lane. OHANA 90 is behind me, guns it, pulls to the left (because I was in 1/2 the lane) and tries to pass me - you know, to get 10 feet further ahead. The ambulance turns. Neither the car in front or I need to continue the right merge. OHANA 90 Lays on his horn, stays right on my driver's side quarter panel and tries to force me into the right lane. I wouldn't go. I show him the siren signal with my index finger and he gives me the middle finger and is screaming like an idiot in his car. The rule is simple, you pull to the right for sirens and lights. Not try to pass everyone who's actually following the law.
