Cars have cups, cup size is uniform? What is the diameter and depth? Are there national standards or industry standards?
This does not have a uniform size, the major car manufacturers and even a brand of various models used in the cup holder will be different
This size is not uniform, the diameter and depth are not the same, this is not yet the national standard, but there will be a range of the industry (the scope of the popular, can be suitable for as many cups and drinks).
Not a uniform size, the standard than the mineral water bottle to be a big point, try the mineral water bottle 3 points 1 height can be a ~! ~
