Carry stuff while in a vehicle
 

I just discovered an interesting glitch. Simply stand near the object you want to carry, and change your vehicle. If you pick up the object before the screen goes white, you will be in your vehicle and still holding the object. You need to keep the right trigger held or else you will drop it also. It's not too useful, since you can't use it in challenges, but I thought I should share it.

Wasn't this already mentioned once before?

I think this found earlier this month...
I could be wrong though!

yeah i found it a while ago. thanks though
