That’s not even close to what I said.
Take a smooth straight 4 lane street with no traffic. One that is engineered to be save for speeds up to 50mph.
Then slap on a 30 mph speed limit. That is an invitation to speed.
You said : “Not so simple when you are driving down a road engineered to be safely driven at 50mph and the speed limit is 30.” So yes you did say that.
