Every time I approach the traffic lights I trust my brakes, factory fitted, probably not looked at in 100,000km's are going to work.
Just saying....
If you want zero risk, stay at home. Even there you may get killed by meteorite or a nest of killer bees.
It seems there is a risk area with the jetpack below parachute altitude, above roll-cage protection. Just like my aircraft 100-300ft after takeoff almost every flight...To be honest I'd rather the jetpack!
