Device： MS XBOX ONE Controller LT/RT work as a same axis. That means if i use LT/RT buttons as throttle/brake, i can't throttle or brake at the same time. One value is postive,the other is negative. When sum of the two values is postive( or negative whether which one is defined depands on details settings ), throttle will be on, brake will be off and vice versa. If LT/RT buttons work independently， it may work properly.
