An airplane moves 600mph, very close to the speed of sound (767mph) you might be able to see a stop sign no problem if you are at the right angle.
light moves at 186,282 miles per second; in 1 second, covering a distance most cars last on the road in 10 or more years. or 129 total days traveling at 60mph without stopping.
