Just an anecdote.
I have a complaint.
Often, as an Englishman in France, I stop at zebra crossings to let passers-by cross the road. What annoys me however is that when you do that, they seem to slow down. You know, they just wander across the road at leisurely pace without a care in the world. Maybe it’s the sun ?
And another thing. When you indicate to move over on the motorway, they speed up to not let you in.
slow down = ralentir
speed up = accélérer
move over = se pousser / déplacer
