What are some good, practical automotive supplies and car gear?

The following automotive products are in no particular order

Polarized sunglasses: recommended for everyone

First things first:It is highly recommended to wear polarized sunglasses when driving in any daylight environment!

I myself am nearsighted, so I need a polarized lens that I can use directly on my near-sighted glasses, and I used to buy the kind of clip-on with a spring, and then I found that it was really difficult to use (I believe that those who have used it have experienced it), until I came across this eyeglasses frame with a magnetically attracted polarized clip-on by JEEP, which is more than just a pair of sunglasses. is also your myopic glasses:

All I can say is, perfect! Its polarized lenses are magnetically sucked, when not in use directly take down and put, use when sucked up, very convenient, one-handed blind operation without pressure, and JEEP this glasses itself wear simply do not be too comfortable and stylish! It has served as my myopia glasses for several years now, and is very lightweight. The problem, though, is that the clip-ons have to be protected and are relatively easy to scratch (the weight of the clip-ons is almost negligible).

However, the comment section is a spitfire, saying that it's too expensive ...... It is indeed too expensive, so I'll recommend 2 more cheap polarized lenses, one with clip-on lenses for nearsightedness, and the other with polarized glasses for day and night.

Recently, in another answer, a friend said he put an anti-reflective mat on his dashboard, so he couldn't see the reflection of the dashboard on the front glass. This brother must not have read my answer, otherwise he shouldn't have not known that this anti-reflective mat would block his secondary airbag, which would bring serious safety hazards (and most likely release pollutant gases). In fact, I emphasized at the beginning of my answer that don't use anti-reflective mats on your car, what you need is a polarized lens that filters out intrusive reflections and doesn't pose any safety hazards!

With polarized lenses (pictured right) you can effectively eliminate glass reflections and reduce sunlight irritation to your eyes.

Front sunshade: unprecedented insulation effect

By suction cups mounted on the front glass near the passenger A-pillar position, when used directly from that side to pull over, across the entire front glass, to stop the sun into . The effect is well, so to speak, although not advertised on the drop 30 degrees so exaggerated, but the difference between using it and not using it if it is not obvious enough you come to me, I rely on it in the summer to continue, otherwise even if it is a morning commute to work in the car is very hot (the sun comes out early in the summer ah)
