Sounds meant to be audible to blind people can be swapped with arbitrary MP3 files? Just another case of "first principle thinking" (i.e. naivete) colliding with real world regulations, with predictable results.
From the recall notice:<p>"While Boombox can enhance the conspicuity of the vehicle to pedestrians, a vehicle that uses Boombox […] may cause the PWS [Pedestrian warning system] to be noncompliant with FMVSS 141, which could increase the risk of a collision."<p>"[S]ounds emitted using Boombox could be construed to obscure or prevent the PWS from complying […]."
