I was nearly run down by an old lady on a mobility scooter today.
She was hurtling along the footpath with a big grin on her face.
Obviously the meds are working.
I see that they have had problems in the UK.
See this link.
As The Old Girl drives her car like a racing driver I imagine that when she gets to the age that requires a mobility scooter we'll have to get a modified one for her.
