Potential fatality / severe injury - roll bar is located too far forward and does not have adequate padding for drivers over 5' 10" tall. A relatively minor accident can easily become a fatality as a taller driver's head will impact the roll bar instead of the headrest. A retrofit providing additional padding is necessary.
