OK - now lets bring it on back to the real world.
Suppose a person is going along a highway - a 2 lanes in each direction, divided highway. (S)He is is going 50. The limit is 70 (common in MANY states) She is NOT speeding, no one else is speeding. The other 350 vehicles per hour are all doing 70. In this example - No-one is SPEEDING!!!!!!!!!!!!!!!!!
However "our hero" is presenting a speed difference of 20 mph. If there is an accident - who's the ONLY one who could potentially have introduced a "bubble" in the flow of traffic? Who is presenting a danger to others? Who could potentially be responsible for some deaths?
You are NEVER going to convince me to stop and just park in the second lane of the 401, while everyone streams on by at 75 mph. Nor to drive at 1 mph in a 70 zone. Or 2 mph. Or 5 or 10 when everyone else is doing 70. I will move with traffic.
Since this is a TOWING thread, not a DRIVING one, if my trailer tires are not safe to operate at prevailing speeds then I should receive a very healthy ticket for knowingly operating an unsafe vehicle on a public road
And yes, a former coworker - who now lives in Westbank got nailed on the Coq connector for unsafe driving for towing his powerboat at 105 kph, thus impeding traffic and presenting an undue hazard to other drivers. Cost him a ton of cash - which he sez was worth every penny as his wife had been ragging on him for going too fast when the cops pulled him over. She thought he was getting a speeding tik, so he sez the look on her face when she found out he was getting nailed for going too SLOW.....
(by the way - big boat - it sleeps 6 and tows skiers, 3 axle
