Want someone to stop tailgating you? Turn on your windshield wipers.

Careful with motorcyclists! My mom did this once and he drove up next to her and gave her a stiff middle finger. To her credit, she didn't intentionally do it -- she just wanted to clean her windshield.

Always carry the roadside essentials in your vehicle.

Jumper cables, a small jack, four way lug wrench, road flares, and maybe a MRE or two.

When renting a vehicle, always record a video of its current condition when you first get in.

This will provide evidence if you ever return it and are accused of damage that you didn't cause.

Have a stubborned oil filter and it‘s too tight to get a wrench in there? Use sandpaper to grip it.

Before embarking on a long drive, give your car a once-over.

Check the tires, lights, fluids, and make sure to have a spare tire (a real one and the tools to change it -- not just a donut tire).

Always learn the side-streets if you travel on a major thoroughfare.

They can, occasionally, be less congested.

If your car is stuck in the snow, use the floor mats to gain traction.

Place the mats in front of your wheels, and slowly drive onto them.

Always keep a spare change of clothes in your car.

Shoes, shirt, underwear, socks, and pants.

Don't ever buy a car on its very first generation.

Typically, the technology is rushed so it can be tested in the field, so that the second generation can be much more stable.
