2022 TESLA MODEL Y — FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

I was driving West bound an the 91 Freeway, just about 1 miles East of the 241 Fasttrack at about 5:30 PM on 30 April 2022. The 241 Fasttrack was shut down for road work and the traffic was averaging about 4 miles and hour, but very stop and go traffic, not a smooth flow. I put the can into dynamic cruise control -- this was done by press down twice on the drive shifter on the right side of the steering wheel. I then took the car out of dynamic cruise control by pressing the drive shifter up once. But I much have forgot I did so as I press the drive shifetr up once again, which puts the can into reverse. I pressed the gas pedal and the car started going backward and I crashed into a vehicle -- I believed the car was in Drive, not Reverse. No one was hurt. My car was undamaged; his 2004 Toyota Corolla had some cracked paint and the left driver side bumper was push back about 3/8th on an inch. I paid the man $450 and he will contact me if he needs more. My complaint is this: the drive selector is being used for drive selection AND engaging and disengaging dynamic cruise control -- it may me to easy to make a mistake where the drive thinks he took it out of dynamic cruise control, but in fact put it into reverse. I do not think the same motion for turning off dynamic cruise control and putting the car in reverse should be on the some stick with the same motion. The only indication is a audible 'tone' when disengaging the dynamic cruise control, but road noise, cabin noise, radio
