Suburbs and Speed Humps

[Jstaleness]

I thought I'd post this as my daughter who is newly licensed within the past few years or so mentioned something.

We were doing our usual driving through areas of Cole Harbour and she said. I don't understand these Speed Humps. They mark the street as 50km zones, but these bumps force most cars to do about 35 or 40 to not launch into space or give the kids in the back a headache.

Is she right? I think so. I'd rather see changes to the limits and make them 40km/h across the board. It seems to work in the areas I have experience in Toronto and eastern Ontario regions.

It's annoying for one, and two, very few are near crosswalks. (I am OK with humps here) Some are just meters before stop signs which makes no sense to me, as I have never accelerated up to a STOP sign.
Ridgecrest in Dartmouth/Cole Harbour is shorter than Bedford Row and has like 4 of them. Overkill.

Is she wrong here? If it's legal to drive 50 then why are we constantly overusing our brakes and then accelerating again just for another hump. Seems inefficient, and if you want to look at it this way, not exactly environmentally friendly.

I'm curious on others thoughts.
