Several things about ADHD promote bad driving (in general) and speeding (in particular). As others have mentioned:
- Stimulation-seeking
- Impatience
- Not paying attention to speed
And I’ll add:
- Running late because of (a) disorganization, (b) trying to do too many things at once, (c) not remembering to schedule travel time, (d) losing track of time
- Not noticing the speed limit signs
By chance, there’s a book titled, “Disciplined Attention.” It’s for remedial driving classes and not intended for ADHD, but the content fits us plenty!
