I thought the v1's arrows were a *perk* as apposed to an actual tool. Now I know why everyone likes the arrows. I was coming back from a delivery, and as I pulled back out onto 20th ave, I picked up KA, saw a cop pass by about 800ft away, and I thought "well, I know ka works now" so I kept going, and it was still going off strong on KA, so I though what I did with my x50, he must have had a rear antenna going too. BUT this is where I came to realise how important the arrows are, it was still flashing the forward arrow, KA! so I thought, well, I wonder where the second cop is. Sure enough, he was coming from the right at the light, and KA pegged again. I probably would have ran that light (yellow) if I had my x50 and the cop may have seen me.
Minor experience, but I now see why the arrows play a large roll.
