What? If you left-click in a place, a small card appears with an arrow that you can click to get directions. If you right-click, you can get directions from or to the place. And if you search, you also get a very visible round button with an arrow and the label "Directions". How is it hard? EDIT: Sorry if this came out as aggressive. I'm just dumbfounded, that's all.
Maybe GMaps is just polarizing software that seems awesome to some people and awful to others? Unless you're a Googler and/or on the Maps team? :) One thing that is absolutely brain-dead is that (in Chrome) I can't type in maps.google.com and tab-search for my address. I can do this with Amazon.com or Netflix, but not an actual Google property? Weird. Another thing that is just bafflingly absent is that GMaps doesn't…
Also I'm not sure but it would seem you have some kind of plugin that might be interfering as GMaps is very smooth on Mac Chrome and Safari.
And you might be single-clicking on the maps which brings up a gray marker to show you more detail of the nearest address to where you clicked. It's easier to just use the scroll wheel to zoom in/out.
And you can just put the address in the search bar and the first result on the results page should be the address detail plus links for directions.
