Which is a road trip to some place very empty in something like a 180º arc. Maybe 225º.
Further, you test in an enormous empty field, as he's doing.
But he also used an extremely lightweight ball projectile — a few grams of 3D printed plastic — because he was only interested in the launch speed. And he pointed it in a direction where there were no people for miles.
As an engineer, if you can't even start a process with sobriety, rigor, and safety in mind, that cavalier attitude only amplifies as you go down the road from experimentation to design to unleashing your ideas onto the public.
It's a harbinger of what is to come if you're being a suicidal idiot during the prototyping phase. If you don't even have respect for your own safety...
And he uses light weight biodegradable plastic instead of steel balls.
Most of his projectiles land in the ground not too far away.
Responsible engineering.
Into the ocean, I would hope
