Q & A

How does holding your car key fob against your head increase its signal range?
-Holding the fob against your head increases its signal range due to the human brain's water content, which conducts electromagnetic waves, amplifying the fob's signal and extending its range up to 85 feet and beyond.
Why do many car manufacturers include a spare traditional key inside the key fobs?
-Manufacturers include a spare traditional key inside the fobs to provide a solution for drivers who find themselves locked out of their car with a dead key fob battery.
Is the belief that driving a red car leads to higher insurance costs true?
-No, the color of a car, including red, has no impact on insurance costs. Insurance premiums are determined by factors like the make and model of the car, driver history, and usage, not the color.
Why is filling up your car with gas in the morning not likely to save money?
-Filling up in the morning does not save money because gas is stored in well-insulated underground tanks, maintaining a consistent temperature and preventing significant expansion or contraction that could affect volume.
What causes phantom traffic jams, and how does frequent lane changing affect traffic flow?
-Phantom traffic jams are caused by the ripple effect of vehicles accelerating and decelerating. Frequent lane changing can force others to slow down, exacerbating traffic congestion and ultimately not saving time.
What is the purpose of the energy management loop in seatbelts?
-The energy management loop in seatbelts is designed to absorb some of the impact in a crash by allowing the threading in the loop to rip open, providing a few extra inches of seatbelt to prevent extreme jerks and minimize the chance of the belt tearing apart.
Why might a driver's check engine light turn on after refueling?
-A check engine light may turn on after refueling if the gas cap is not screwed back on properly, leading to a release of vapor and potentially triggering the evaporative emissions control system (EVAP) alert.
Do dirty cars perform better than clean cars in terms of fuel efficiency?
-No, dirty cars do not perform better in terms of fuel efficiency. While the theory suggests that dirt could make a car more aerodynamic, in reality, it disrupts the car's designed aerodynamics, potentially increasing drag and reducing fuel efficiency.
What are some hidden features or 'auto easter eggs' found in cars?
-Auto easter eggs include hidden umbrellas in Skoda models, built-in ice scrapers, retractable license plate drawers for bicycles in Vauxhall vehicles, and parking cameras hidden behind the Volkswagen logo.
How does motion parallax affect drivers' perception of speed?
-Motion parallax causes objects closer to move faster in the driver's field of view than those farther away, affecting speed perception. Truck drivers, being higher up, may perceive themselves as moving slower and tend to drive faster, while sports car drivers may drive slower due to the opposite effect.
