This makes them more vulnerable to environmental factors like rain.<\/p>\n<p>\u201cThese systems are normally evaluated in ideal operating conditions. The problem with that is people don\u2019t always drive in perfect, sunny weather,\u201d said Megan Cooper, spokeswoman, AAA \u2013 The Auto Club Group.<\/p>\n<p>\u201cWhile these systems can be helpful for drivers, they are not perfect. So it\u2019s important that drivers be aware of their vehicle\u2019s limitations and remain fully engaged while behind the wheel, regardless of the weather,\u201d Cooper stated.<\/p>\n<h3>AAA\u2019s Wet Weather Tips<\/h3>\n<p>Wet conditions present challenges to drivers regardless of whether their vehicles are equipped with safety systems. AAA recommends using extra caution in slick conditions by doing the following:<\/p>\n<ul>\n<li>Keep windshield clean and ensure that wipers are not streaking the windshield.<\/li>\n<li>Slow down and avoid hard braking and sharp turning. If possible, follow in the tracks of other vehicles.<\/li>\n<li>Increase following distance to 5-6 seconds behind the vehicle ahead.<\/li>\n<li>Do not use cruise control in order to stay alert and to respond quickly if the car\u2019s tires lose traction with the road.<\/li>\n<li>If the car begins to hydroplane, ease off the accelerator to gradually decrease speed until the tires regain traction, and continue to look and steer where you want to go. Don\u2019t jam on the brakes\u2014this can cause further traction loss.<\/li>\n<\/ul>\n<p>[470center]<\/p>\n<h3>Previous AAA studies on ADAS Technology<\/h3>\n<p>Previous AAA testing of vehicle safety systems in both closed-course and real-world settings show that performance is greatly impacted by driving scenarios, road conditions and vehicle design, finding issues like the following:<\/p>\n<ul>\n<li><a href=\"https:\/\/urldefense.com\/v3\/__https:\/newsroom.aaa.com\/2018\/11\/americans-misjudge-partially-automated-driving-systems-ability-based-upon-names\/__;!!A1OrVxnpM0w!UqBFBs03x2W1SDaXM6JM3BSkVHZlEAZGkwvxq1_ro1QTsxAPZ6Ek9gpakDp5OdQ$\"  target=\"_blank\" rel=\"noopener\">Struggling to stay within in a marked lane<\/a> in moderate traffic, on curved roadways and on streets with busy intersections<\/li>\n<li><a href=\"https:\/\/urldefense.com\/v3\/__https:\/newsroom.aaa.com\/2019\/10\/aaa-warns-pedestrian-detection-systems-dont-work-when-needed-most\/__;!!A1OrVxnpM0w!UqBFBs03x2W1SDaXM6JM3BSkVHZlEAZGkwvxq1_ro1QTsxAPZ6Ek9gpa0_6CeWE$\"  target=\"_blank\" rel=\"noopener\">Failing to stop for pedestrians<\/a> in common scenarios like crossing in front of a vehicle, a child darting out between two parked vehicles, or walking at night<\/li>\n<li><a href=\"https:\/\/urldefense.com\/v3\/__https:\/newsroom.aaa.com\/2020\/08\/aaa-finds-active-driving-assistance-systems-do-less-to-assist-drivers-and-more-to-interfere\/__;!!A1OrVxnpM0w!UqBFBs03x2W1SDaXM6JM3BSkVHZlEAZGkwvxq1_ro1QTsxAPZ6Ek9gpa0FGH9QM$\"  target=\"_blank\" rel=\"noopener\">Colliding with a simulated disabled vehicle<\/a> and instances of coming too close to other vehicles or guardrails<\/li>\n<\/ul>\n<p>AAA\u2019s research continues to show that vehicle safety system performance varies widely, reinforcing that they are not a replacement for a fully engaged driver.<\/p>\n<p>\u201cAAA recognizes these systems have the ability to lessen the chance of a crash and improve the overall safety of driving,\u201d continued Cooper. \u201cFine-tuning their performance and providing drivers with a more consistent experience will go a long way in unlocking their true potential.\u201d<\/p>\n<p>[470center]<\/p>\n<h3>Optimizing Use of Vehicle Safety Systems<\/h3>\n<p>It\u2019s essential for drivers to be familiar with how their system operates. AAA urges drivers to take time to read the vehicle owner\u2019s manual to learn <strong>when<\/strong>, <strong>where<\/strong> and <strong>how<\/strong> to use them.<\/p>\n<ul>\n<li>Vehicles with ADAS cameras located behind the windshield, like those used in this research, \u201csee\u201d the same things a driver does.<\/li>\n<li>If the windshield wipers are worn and streak across the window, this could interfere with the system\u2019s performance.<\/li>\n<li>Drivers should regularly inspect their wipers and replace at the first sign of streaking, chattering or if the blades appear hard and brittle.<\/li>\n<li>A good rule of thumb is to replace each year, especially in hot, sunny climates or if a vehicle sits outside all day.<\/li>\n<\/ul>\n<h3>About AAA &#8211; The Auto Club Group<\/h3>\n<p>The Auto Club Group (ACG) is the second largest AAA club in North America with more than 14&nbsp;million members across 14 U.S. states, the province of Quebec and two U.S. territories.&nbsp;ACG and its affiliates provide members with roadside assistance, insurance products, banking and financial services, travel offerings and more.<\/p>\n<p>ACG belongs to the national AAA federation with more than 62 million members in the United States and Canada.
