My husband and I were waiting in town in the taxi line when one of the drivers started reversing his radiotaxi into us. We assumed he could see us however when he did not stop I started tapping the back of his car to avoid being hit. My husband and I tried to move out of the way as quickly as we could but the cab was reversing too quickly. The radiotaxi driver then got out of his car and was yelling in my husbands face asking "do you want to die tonight?" We tried to explain that no we did not want to die which is why we tapped your car with our hand so you do not hit us. I was shocked that this driver couldn't just speak to us in a civil manner.
