question: Why do SUVs get rain on the rear window at highway speeds?
comment: The steep drop off at the rear of the vehicle can create an area of low pressure which actually pulls air (and rain) back toward the vehicle [like this.]( URL_0 )

   BULLET::::- Episode 9: Poor weather, this time in the form of heavy rain, once again caused problems for Team VW. Their lack of windshield wipers and a defogger made it very difficult for them to keep their windshield clear. Their flip up "safari style" front windows also constantly leaked water into the passenger compartment. Team Corvette sustained minor cosmetic damage to their front bumper from accidentally hitting a tire barrier during the challenge.

   BULLET::::- In higher rainfall areas, the increased camber required to drain water, and open drainage ditches at the sides of the road, often cause vehicles with a high centre of gravity, such as trucks and off-road vehicles, to overturn if they do not keep close to the crown of the road
  
  BULLET::::- Excess dust permeates door-opening rubber moulding breaking the seal
  
  BULLET::::- Lost binder in the form of road dust, when mixed with rain, will wear away the painted surfaces of vehicles

   This issue was the subject of a Class-action lawsuit in the U.S. State of California.
  
  In 2010, the United States Judge Howard Matz ruled on the settlement about this issue.
  
  The air/water duct is drained by a reed valve, which if clogged can cause water to overflow into the passenger compartment. Other things that can cause water to enter an S-Class interior include the air conditioning condensation drain tubes

  BULLET::::- 2009–2011: Several vehicle models were recalled in the 2009–2011 Toyota vehicle recalls, which resulted in suspension of production and sales of many of Toyota's most popular models, including the Toyota Corolla, Toyota Camry, Toyota Tacoma pickups, Toyota Avalon, Toyota Matrix, Pontiac Vibe, and more.
   Some drivers have been known to draft behind other vehicles, particularly tailgating larger vehicles, to save fuel. For example, hypermilers using this technique can achieve 75 mpg or more (a 10% increase in efficiency of certain hybrid vehicles). Some sources say that the most common tailgating does not save gasoline even at freeway speeds because one is likely to accelerate and brake so frequently that any aerodynamic savings are lost through the brakes.

   BULLET::::- Episode 5: Teams were affected by light snowfall in the early morning and freezing temperatures through the first part of the day. Team Solstice's low ground clearance added to difficulties in the snow. Team VW's vehicle lacked a heater, which left both teammates very cold and caused ice to build up on their windshield. Team Dart's repair job from the previous day's rollover left many spaces through which freezing air entered the passenger compartment.
   In 2012, General Motors and Isuzu recalled more than 258,000 SUVs in the U.S. and Canada to fix short-circuits in power window and door lock switches that could cause fires. The recall covered TrailBlazer, Envoy, Rainier, Ascender and 9-7X SUVs from the 2006 and 2007 model years. The SUVs were sold or registered in 20 U.S. states, Washington, D.C., and Canada, where salt and other chemicals are used to clear roads in the winter.

   BULLET::::- "Rainfall continuity" – the more frequent and extended are the gaps during the event where no rainfall occurs, the higher the likelihood that potential stemflow volume is lost to evapotranspiration; this is also governed by air temperature, relative humidity and most significantly, wind speed
  
  BULLET::::- "Rainfall intensity" – the amount of total stemflow is diminished when the amount of rain in a given period surpasses the capacity of the flow paths
   This will reduce lift and increase drag. All three factors increase stalling speed and reduce aircraft performance, making it very difficult to climb or even maintain level altitude.
   Poorly performing weatherstripping should be reported to the car dealership if the vehicle is under warranty, as fixes may be known.
  
  Section::::Automotive weatherstripping.:Materials.
  
  Automotive weatherstripping is commonly made of EPDM rubber, a thermoplastic elastomer (TPE) mix of plastic and rubber, and a thermoplastic olefin (TPO) polymer/filler blend. Sunroof weatherstripping can also be made from silicone due to the extreme heat encountered by automobile roofs.
   BULLET::::- Rain: precipitation that reaches the ground as liquid, often in a precipitation shaft.

   A class action lawsuit was filed in California state court against Mercedes-Benz alleging the defendant has sold Mercedes-Benz Sprinter models 2500 and 3500 with water that leaked from the air conditioning unit in the roof onto the passenger area. The leakage of air conditioning unit was also discovered on Dodge Sprinter made by Mercedes-Benz from 2003 through 2009. The lawsuit affected California residents with the rooftop AC units and Sprinters equipped with the rear AC.

   On the show "MythBusters", drafting behind an 18-wheeler truck was tested and results showed that traveling behind the truck increased overall mpg efficiency by 11%. Traveling behind the truck produced a 39% gain in efficiency. Additionally, on the same episode, Mythbusters demonstrated that it can be very dangerous for the following car if one of the truck's tires (or their recaps) delaminate, as the chunks of ejected rubber can be large enough to cause serious harm, even death, to a driver following too closely.

   BULLET::::- Rain – precipitation in which separate drops of water fall to the Earth from clouds, a product of the condensation of atmospheric water vapor
  
  BULLET::::- Snow – precipitation in the form of crystalline water ice, consisting of a multitude of snowflakes that fall from clouds
  
  BULLET::::- Freezing rain – precipitation that falls from a cloud as snow, melts completely on its way down, then passes through a layer of below-freezing air becoming supercooled, at which point it will freeze upon impact with any object encountered

   In April 2013, Betsy Benjaminson, a freelance translator working for Toyota to translate internal documents, released a personal statement about Toyota covering up facts about the sudden unintended acceleration problem. Benjaminson stated she “read many descriptions by executives and managers of how they had hoodwinked regulators, courts, and even congress, by withholding, omitting, or misstating facts.” Benjaminson also compared Toyota’s press releases and mentioned that they were obviously meant to “maintain public belief in the safety of Toyota’s cars—despite providing no evidence to support those reassurances.” This public statement was released when Benjaminson decided to name herself as a whistleblower after she had been providing evidence to Iowa Senator Charles Grassley.
