I would really like to see the ability to select a range for the miles to be traveled a day to the trip planning process. I find it a hassle to manually do it myself

I would like to be able to enter how many miles/hours I can drive a day on my trip to have the option to search that area for fuel/accommodations/attractions. There is no mile scale on the map making it very hard to figure out how far to make the next stop. Google maps has a nice option to measure on their map by right clicking and bringing up a menu that has measure distance. You then click on the map once then move along your route and click again and it gives you miles. You can click as many times as you want adding miles along your route. At the least put a useable scale on your dang maps.

Planning a road trip means building an itinerary, especially splitting the travel into desired leg lengths. That's entirely missing here - even the list of hotels is just a bunch of ads, sortable by distance from my home but not filtered to the route and sorted by distance along it.
