I honestly didn’t think anyone would solve my code word of getting yogurt....
Hahahah
At first I was reading your description and thought you were in the wrong to make the left lane change to turn Right. but I misinterpreted it like some other readers who should have used google maps to play the situation out.
If you were afraid to hit your tires on the curb, naturally anyone would go the far left Lane on Wilderness Oak while turning from Blanco RD. What provoked that idiot in the mustang? Who knows. Maybe you didn't do anything wrong and the dude was just high on drugs or have mental issues. Don't assume everyone is normal like you, never make that assumption on the road.
And in Texas its quite more dangerous with their PRo gun situation. So it was better you got hit on the passenger side with that metal rod than your gf getting hit with a gun. You got lucky that this idiot wasn't packing, otherwise it would be a nightmare with someone like that on your ass.
Things you should do if it happens again.
1. Get a dashcam, in case some incident happens again, you got their license plate and can report it to the cops or insurance companies if there is damage.
2. Get your gf to start recording or call the cops if you feel there is some kind of threat on the road. If the dude on the mustang sees someone on the phone, he probably would get spooked and cool it off.
3. if they feel like they are tailing you or trying to keep up with you, don't do what he thinks you would do. Throw him off and move elsewhere or go slower to where he gets impatient and drives off. Make the first right or left turn so he doesn't follow you if the guy is in front. He would have to do a U turn to catch up to you.
4. Don't be scared, stay calm and don't be angry, anything can cause you to lose it to idiots who are trying to play mind games with you. Could cause an accident.
I had an incident recently where I was on a three lane road, this person behind me was coincidentally an idiot with a mustang too. Since I was near approaching the light to make my left turn on a one left turn only lane, the mustang behind me got offended because he tried to turn in the left lane quicker than me from much farther back. So he felt his personal bubble got invaded when i made the signal and turned left. (some cases people actually speed up when they see that blinker blinking
knowing they should let you pass but they tell you to EFF off instead )
As I was making the turn. this street was designed very stupidly by street engineers. It would be confused at if it would want to be a two lane road or a one lane road. Sometimes the roads would narrow and require the right lane to merge to the left lane. then later becomes two lane again with another left lane merge from the right lane. Since i knew the stupid road. I would just stay on the left lane to avoid being the one on the right to make a quick left turn where the right lane suddenly ends.
The guy in the mustang didn't want to be behind me, so he tried to do a quick right lane and speed up to do a left lane change to pass me. When he tried to do that, there was another vehicle in the front of him on the right lane that he didn't see since he was too focused on my lovely 4runners behind, so it slowed him down. he got very irritated. So he was forced to make a left turn lane merge behind me, then the road would become two lanes again for a brief period before becoming one. I can always tell when he presses the accelerator when his loud muffler would roar. so this time he gunned the pedal hard on the right lane to pass me on the left.
Thunder was roaring on my right and he went flying to the left in front of me. We stopped at a red light and he would look at his side mirror with his angry face at me from time to time, trying to make sure where I am at so I don't get past him on a one lane road. Not my fault that i knew the roads better than him. Green light comes and he goes, but he is stuck behind another vehicle in front of him while monitoring me in the back. He was thinking i was going to follow behind him behind and get annoyed. I actually had to make a left turn soon, so I did a left and caught up to him on the left turn only lane.
At this point, he probably thought I was going to pass him on a left turn only lane, so it threw him out of his plans to keep me following him from behind. He couldn't speed up because of the vehicle in front of him. I don't think he even anticipated me going left because it was a small one lane only road both ways with dirt and nothing else .I didn't look at the moron's face when I was caught up with him, I just knew I had to turn left. So before I made the left, since he was too busy monitoring my actions from behind. I figure I give him the universal sign language of truth up closer to where he could see me and to tell him goodbye as I went my way and he went his.
I shouldn't have done the last bit, but some people just deserve it. If they are angry, let them be angry. It shouldn't ruin my day for idiots who likes to dominate the road with their sports car. Once i see sports cars like that. I just let them pass and cut, its just their natural driving habit to be A-holes. Just be glad you are safe and not sorry. So take the situation you've experienced, and learn from it and to de-escalate it before it gets heated
