** when Ramps and/or Minor Highway and above are involved = '''Exit Right / Keep Left''' instruction for right-hand drive countries, '''Keep Right / Exit Left''' instruction for left-hand drive countries
* Approximately '''0''' degree departure angle = '''no navigation instruction'''
These angles allow us to clearly depict the desired result (turn vs. keep) while staying away from the angles that cause uncertain decisions from the routing algorithms. For example, since 45 degrees is a tipping point for the algorithms, a 44.5 degree angle will behave very differently than a 45.5 degree angle, although they will look identical to the eye.
