Just my opinion, but just a cage in the rear only is no real protection. I agree offroad is an excellent reason for a cage instead of just a rollbar. The Flipside of that is your windshield frame is little to no protection in case of a roll over. The strength of the windshield is nothing compared to that of the vehicle. Worse case scenario it folds into your lap. I see this perspective as more influential in terms of around town driving than offroad.
Here’s another way of looking at it:
- 25% of the time you’ll have rear passengers
- 50% of the time you’ll have a front passenger
- 100% of the time you’ll have a person sitting in the drivers seat.
It’s not to say that the driver is more important than the passengers, but it just more likely they will need more protection than the windshield will provide.
***Full Disclosure*** I completely understand these are far from safe vehicles. I don’t believe you can make it as safe as the tin cans put out today. I’ll step off my soap box now.
