 The Highlander has poor visibility to the rear, passenger side, and backup camera screen sucks. The visibility out the rear window is like the light at the end of a tunnel and is almost useless for seeing out the back. The rear window is designed for looks and style rather than safety visibility concerns. You cannot see cars directly behind with the rear view mirror.It is very difficult to see the images on the backup camera screen during the day and night. You have to strain your eyes to look at the screen to try and make out what is behind.  This creates a problem of spending too much time looking at the screen and ignoring the other surrounding areas. The screen's visibility is not great when it is darker, rainy or foggy. It is difficult to see low cars or any vehicle on the passenger side. The blindspots are major problems when preparing to change lanes. It is very difficult to see cars in the blindspot at night or during any rainy weather(the passenger side mirror is not enough). As you strain to see the car in the blindspot, you will ignore the cars in front and a front collision is possible.I wish I had bought the blindspot sensors and front collision sensors. I wish there was a retrofit.Because of the visibility problems, the Highlander is not the safest or easiest vehicle to drive. From what I know now I regret getting the Highlander without the blindspot and front collision sensors.It is very unsafe to accelerate too fast on the Highlander. If you accelerate too fast your grip on the steering wheel could be overcome and the front wheels will turn uncontrollably from side to side. You have to grip the steering wheel very tightly when you accelerate to maintain steering wheel control. You can easily lose control and crash by accelerating too quickly. I never had this problem on any car I have driven. It is a safety defect.I use a USB chip for my music and the audio just gets stuck and nothing happens. I cannot turn it off or reset it. I just let it alone and it just starts working again after a few minutes. I would fire the designers of the Highlander.I would never buy a car/suv/truck/van without blindspot detection. I would never buy my Highlander again.
