I'd call that first car Orange Crush but I'd add 'and stab'. Both cars lack critical support members, whether they can manage to survive a rollover or not, but the second car is better thought out.What an indescribable horror if the first car hits REALLY HARD the wrong way. Instant apendectomy & colostomy as those control arms come ramming into your guts? One should never design such that a component can ever reach the driver in a crash. Scary with that ultra-long shock on the rear too, in that respect. Could end up with your head resembling a shish-kabob? Should have a loop of tube around them as a guide for where they'd go if top shock mount broke loose at impact or a hard landing, also to prevent pole vaulting.Also needs diagonal supports at lower points of roll cage, from about steering wheel height down to top rail at a minimum in front, slightly higher and connecting farther forward on top side rail at rear hoop. Without those a weird end-o could collapse the cage at a top-rear impact. The sides appear to be ladder frame sections by the screws in the side panels? I'd say triangulation is much preferred, using diagonals? Would also be nice to have a horizontal tube about shoulder height behind driver/passenger for some 5-point belts and to help prevent seat fold-over? I would have also run a horizontal bar across the forward shock support hoops to stabilize. All that would only add what, maybe 10 pounds?Second car could use the front & rear diagonals too, and both cars need a u-joint in the stab-me-hurt-me steering shafts. Second car gets huge extra points because no frame or chassis member could intrude into driver seating area to impale or injure driver. It could use a horizontal cross-chassis tube right about at rear mounting of front diagonal roll cage support tube, where verticals tie in, to cut down on frame flex.

IMO the worst thing that is done is the practice of welding the joints in 4 90* arcs.
