[2020] Travel time

Commercial and industry work even if their workers are at home, so in that regard it doesn't really make a difference. But when it comes to delivering goods in time, it does matter. A commercial building that runs out of goods will shut down until it gets new goods, and in that time you won't receive tax revenue. The same goes for industry - both getting resources and emptying their internal storage fast enough.

Both have a time frame that this can happen within as they send out requests before being empty. As long as trucks make the timer, there isn't a problem. Having it be much faster than the timer doesn't really do anything - other than ofc mean you have fewer vehicles on the roads, which tends to mean a smoother running city.
