Electronic Accelerators such as the Accelerator Rings and Electronic Radial do not have this problem as the mechanical brake bar can be routed around the airbag. This is the preferred option as all safety systems are maintained.
However, for the case where electronic controls are not preferable, the Knee Intrusion Air-bag Compatible Hand Controls system features a removable connecting rod that temporarily disables the Knee Intrusion Air-bag ONLY while installed. This rod is removed with 30 seconds when an able-bodied driver takes the wheel and the Knee Intrusion Air-bag is re-enabled.
