How is daily driving caged car extremely dangerous?
Cause your head isn't as hard as the tubing used to make the cages, people don't normally daily drive with a helmet on, and some people drive caged cars without bucket seats/harnesses. <-- which is a horrible move.
"A roll cage is part of a four-piece safety system - together, they are incredibly safe but separately, they can be deadly.
The pieces are:
Roll cage with properly placed padding
5, 6 or 7 point harness
Fixed-back race seat or back-brace supported recliner
Helmet (not dangerous by itself but very necessary in a caged car)
As mentioned, when bone meets cage tubing, the tubing generally wins. An improperly restrained driver has a greater likelihood of meeting the roll cage than one using a harness. The harness works best with a fixed-back race seat or a seat with an attached back-brace because the weight of a driver adds a huge amount of stress to a seat - as the car is subjected to various loads, the seat back on a recliner can break, causing a sudden recline into the main hoop. The helmet protects your noggin...
In a non-caged car, harnesses and/or a race seat are dangerous because they hold the driver in place. This sounds like an oxymoron until you think about the E36 BMWs that collapse to the cowling when they roll over. With a race seat or harnesses, the driver & passenger cannot dive for the centre of the car and their only saving grace is that the factory seat will most likely break and go into full-recline (also known as "Love Mode"). With a properly mounted race seat and no cage, the driver's head and the seat become the highest point in the car during a rollover.
That having been said, I've read numerous accounts of "Dude, a cage saved my life - I'll never drive without one". While some of these accounts are convincing, it's much akin to the argument that seatbelts kill because "my cousin was drivin' drunk when he flipped his Camaro 15 times - if he hadn't been thrown free, he'd have died in the fire". I think I take the risk of driving without a cage while wearing my seatbelt. "
Got that for a vwvortex on the subject of daily driving a cage.
I would never daily drive a car with a cage, but then again that's just me. Just food for thought I guess, nothing to take serious. /end
