What's a pro tip all car owners should know?

When your screen is frosted over, put both the sun visors down. Helps trap the hot air at the windscreen.

Your car has a Cabin Air Filter that's usually hidden behind the glove box. If your car smells musty or bad, there's a decent chance that thing is clogged like crazy and it's only about $15 to swap it out yourself. I found a freaking dead mouse behind mine last time I changed it.

Make sure the check engine light turns on when turning the key.
Sometimes the sleazy user car dealers will cut the cord on the engine light when things are shitty so it looks like there's nothing wrong with it.

Your ignition doesn't like 10 lbs of keys and keychains hanging from it. It will wear out over time.

The oil pressure light isn't just a reminder to check on in a few days. That's a pull your ass over now the engine is out of oil light.

Most loaded trucks WILL NOT stop on a dime like a car. If you can't see the trucker, the trucker can't see you. A truck tire blows up with the force of a grenade. Trucks always have the cheapest tires available, so when you're overtaking a truck STEP ON THE GAS! Don't dilly dally near the trailer tires waiting for one to explode and obliterate your passenger.

"When having someone follow you in their car..."

"... let them lane change after you start signaling. That way, they can let you in and you don’t risk getting separated."

when someone if following you in their car, let them lane change after you start signaling. That way, you can lane change in the other direction and lose them more easily.

Whenever I see these posts it makes me wonder why people don't just give out addresses and let the other person use their GPS.

THANK YOU!!! I need to have 10 cars follow me tomorrow and I had no idea what I was going to do!

LPT - don't ever let someone follow you or follow someone else. Make sure each party has the directions.As an EMT, we routinely had family member tell us they would follow us to the hospital.
NO.
I cannot tell you how many times we had people follow us and would run through a red light because it was yellow when we went through. I do not want to be responsible for someone getting into an accident because they feel they have to mimic every lane change and turn I make. People get into a strange tunnel vision when they are trying to follow another vehicle and some how forget traffic laws and ignore all other cars on the road.
