Returning from some R&R in lovely Mexico I must share some thoughts about the road (speed) bumps (humps) they so love and spread in large quantities around there.
A lot has been said about Mexican driving and law enforcement. I can’t comment about that because I didn’t see there anything I haven’t seen elsewhere. The theory is that the people there (like everywhere else I guess) like to drive fast and the police is powerless against it, and so they resulted to a lot of bumps – so far, makes perfect sense. Bumps are located in residential areas and on highways as they cross small towns and villages. But they put very bad bumps.
The “government issued” ones are more like a small table-top mound as seen in this clip , and I must say that as long as you come slowly (victory!) it won’t break your car. It does make the flow of traffic really slow, but I guess you can’t really be too healthy.
The common ones are as below and are half piped monstrosities (sometimes built from real metal pipes in the road…) that can be found in most towns and will demolish your suspension if you come at them in anything but near standing speed.
Small, sea shore communities can opt for a very cheap and mobile solution that remarkably has the same results as the half pipe wonder – a ships rope, dunk in tar and spread across the road. It may look flimsy at first glance but in reality it’s as sturdy as the cliffs of moher.
And in some places you find the omnidirectional bump that makes sure your vehicle will sustain permanent damage if going above snail speed. Locals warn of this one in particular.
And I spared you the normal, world wide vibrating stripes and nicely shaped bumps we all know and love.
I can tell you out of experience of driving a rented car for 2 days that while I got a small, relative new car with ~7500 km on the clock, that drove surprisingly well and after some 800 km + about 80 bumps I returned it with a strange clicking noise every time I slowed down or accelerated. That car was not built for the road toppings of Mexico. I doubt any car is.
My point is that most of the bumps I (and my rented car / scooter / golf cart) encountered did made me slow down (or suffer the result of not) but the same affect could have been achieved with normal bumps that wouldn’t render your vehicle suspension-less after just a few thousands of kilometers of driving. It’s like they are trying to find work for the suspension and exhaust mechanics of the great federation of Mexico.
