Why don't cars have back windshield wipers?

Windshield wipers were invented in 1903 by Mary Anderson, a 19-year-old schoolteacher from New York. While driving through a rainstorm, she realized that the glass on her vehicle was so dirty that it was obstructing her view of the road. She devised a hand-operated device to wipe the windshield clean and patented it two years later.

It was the first motor vehicle wiper ever made and came about almost entirely by accident!

The style of the modern car windshield

The modern car windshield was invented by Henry Ford in 1912. It was designed to keep the occupants of a vehicle dry in case of rain, and it has remained largely unchanged since then, with only minor variations over time.

The windshield is placed so that its bottom is at eye level for most people; this allows them to look over it without having to raise their heads too much. The top of the glass is set far enough below eye level that passengers can see out clearly even when seated upright in their seats (this makes sense since humans are not able to bend backward like birds).

Wipers have been added to some vehicles in recent years.

There are a few vehicles that have rear wipers, but they’re typically reserved for luxury cars like the Mercedes-Benz S-Class and BMW 7 Series. In these cases, the wiper is more of a design element than an essential safety feature. The main reason is that it’s difficult to make rear windshield wipers work effectively on all cars. The design and placement of the windshield will affect how well they operate, so there’s no one perfect solution that works universally across all vehicles.

Safety concerns

The primary concern here is safety. If rear wipers were added, they would likely have to be controlled by the driver and could potentially become an obstruction for other drivers on the road. As you know, it’s illegal to drive with distractions like cell phones and eating in your car—so adding rear-facing windshield wipers would just add another potential distraction.

Also consider that when you’re driving behind someone else on a rainy day, it can be difficult to tell how fast they’re going even if their speedometer light comes on when they’re driving over 40 mph (64 km/h). If we had rear wipers that were operated through a switch inside of our cars, there would definitely be some potential problems with visibility—especially because drivers are supposed to keep their eyes trained on the road ahead at all times while driving!

Rear wipers could be obstructive

  • Rear wipers could be obstructive for other drivers on the road. When you’re driving at high speeds, you can’t afford to have your vision obstructed by rear wipers. You need to be able to see as much of your surroundings as possible in order to avoid accidents and stay aware of what’s happening around you. For example, if a car is coming up behind yours and needs to pass, but it can’t because there’s a large wiper obstructing their view through their rear window, they may have no choice but to pull over until it passes or pull into another lane (which takes them out of their way). Either way, it causes more traffic congestion which makes everyone late!
  • Rear wipers could cause other drivers to lose control of their vehicles. If someone looks back while they’re driving and sees that their rear windshield has been blocked by a large windscreen wiper blade, they might panic because they don’t know what’s behind them anymore! This could cause them to swerve out into another lane and possibly hit another driver or get themselves into an accident!

Modern car windshields

Modern car windshields are designed with safety in mind—they are large and shatterproof so that they can withstand impact from other vehicles or objects such as debris on the road. Due to these features, it is nearly impossible for something like raindrops or snowflakes to cause damage if they were falling directly onto your back window while driving forward at speed (depending on how fast you’re going). There is also very little chance that insects would hit your window because they are too small relative to its size—and even if one did hit it (due out of sheer luck), there would be no way for them to get through without being crushed first!


So, why don’t cars have back windshield wipers? It’s a good question! While there were some safety concerns with rear wipers, they aren’t the only reason. Rear wipers are also distracting to other drivers on the road and could be obstructive depending on your vehicle. In general, it’s just not worth adding a feature that might cause more harm than good in most situations.
