Age isn't an excuse. Mr Magoo here couldn't even reach half the speed limit on any road. 30 in a 60 is NOT acceptable. If your driving skills are so bad you can't drive at it even near the limit then what are your reaction times like?
Check the highway code. Then get this old man off the road before he kills someone.
Fiat actually put model details on the car so you don’t need to and in any case it’s not really a car that makes others jealous.
