gta sindacco chronicles bug (read the description) 

I got into the car on the passenger side (if I remember correctly) and I disappeared. The car's AI along with its pedestrian got scared because of a shooting and drove away as you can see. The only thing I could do was toaccelerate with the X but the only effect was to make the acceleration noise without actually accelerating the car. I was able to change the radio. I couldn't get out of the car even when it exploded.
