Just mentioning..
If you get pulled over, for whatever, and have to stop at the discretion of the LEO involved,you may nd 9 out of 10 times, you have to park in a precarious position, where bike balance on side stand, or dismounting to root thru your bags, is a CDA waiting to happen, and the LEO ain't gonna help you upright you now horizontal machine, and even if you get a ticket, it still isn't worth dismounting for, to appease the interest of Jonny Law...
Keep it where you can retrieve it, and hand it to him... just personal experience.
Now, personally, if I am stopped, and an officer asks for registration, I simply say I have to sit here as long as you are out of your air conditioned car, here is my drivers license, I'm wearing a moon suit, go back, run my plate, and my license, and be quick about it, please officer...
If they demand an insurance card, I have it in my sleeve, but I still say, oh, no problem, is your office down the road? If not I'll show ya, but I do have 36 hours to provide that, I can stop safely and dig it out at the depot....or, pull it out and hand it to him.
I don't get stopped much.
