Why do big, heavy vehicles such as trucks kick up more pebbles

[raccoon]

on the interstate than regular cars do?

1. Bigger Tires

Bigger gaps in the tread of the tire.

2. More Wheels

Less fenders.

3. They hate our freedoms ... 9/11 changed everything ... It's Clinton's fault

wait, that's the GOP's answer for everything ...

4. And they go further because of more pressure exerted by the tyres

is my guess - they're playing tiddlywinks with the pebbles.

5. Bigger contact patch. More rubber in contact with the road. n/t

[soothsayer]

6. and sometimes they're carrying them (say, dump trucks)

[rock]

7. Scale/Size

To see what I mean, imagine a remote controlled model car on the the interstate. See, it hardly kicks up anything.

8. my car has a GIANT FREAKING PEBBLE MAGNET

I'll be driving down the road minding my own business and all of a sudden, bricks, cinder blocks, TRS-80's, rebar, immigrant crossing signs, nuns with strollers, all KINDS of weird shit comes hurtling through the air, crossing lanes, doing figure eights in the form of two figure fours to head straight towards my windshield at well over escape velocity. In fact if just one of those damn lawn mowers or dresser drawers or whatever the hell comes flying at me next actually MISSED my car and was able to stay level to the horizon that fucker would be in orbit and those little bitty ISS astronauts up there would be like, what the hell is a high top tennis shoe doing flying around out there oh shit it's heading straight for us, sha mack.

It's fucking supernatural. There is no law of nature that can explain it. Ah sware.
