Just my annual rant:
I've graduated from a scooter to a rollator (and sometimes a cane). My annual rant is this: LOOK WHERE YOU ARE GOING.
Seriously, the # of years, back when I used a scooter, that I had some yahoo step right in front of me, causing me to have to quickly stop (and praying the thing WOULD quickly stop) when they could have watched where they were going... it's not any easier with a rollator... you're relying on my legs stopping progress fast - and perhaps causing me (or whomever else) to sprain an ankle.
So please... look where you are going.
