Ever since I installed AutoCAD 2015, I noticed that I seemed to be mistyping the commands at the command line. I finally noticed that there was a delay when typing information into the command line.
This would result in the erase command being issued instead of the extend command, or the traverse command instead of the trim command.
I figured out how to solve this bug.
If you enter the command "inputsearchoptions" and uncheck all of the boxes, there is no longer a delay. You lose all of the fancy new features, but the software begins working as it should.
I changed my delay time (to 2000 milliseconds).
A startup delay I don't like is RIBBONBGLOAD, I change it to 0.
I'll give that a try.
On a different subject, while I might have your attention...I have a question.
I am playing around with using the tracking command to save time having to erase construction lines. I think it will be a big time saver.
Lets say I have a skewed line (shown in yellow). I want to start another line anywhere and be able to have it snap to the intersection of where display ray and the skewed line intersect.
Is this possible without using a custom lisp routine? Currently I have to draw the line long and measure to something else from the intersection. Then erase the construction lines.
After you pick the second point, you can select you line that you just drew and use the grip to move the endpoint to the desired intersection without measuring.

I have been using AutoCAd since Version 2.15 in 1985 and don't think I have drawn more than 10 "construction lines" in that time period... What do you draw them for?
I did not explain well enough what I am trying to do.
Currently I do things with brute force, drawing construction lines/circles.
Here is an example, where I am trying to determine the elevation of a point in a cross section at an offset of 16.67' left. I realize there are easier ways to do the same thing. This is just an example.
I am trying to eliminate having to draw and erase the magenta construction lines.
If I were to issue the distance command, then type "TK", I could select the zero intersection of the section grid, then type an offset distance, then select the point at which a vertical line intersects my finish grade, then pick perp. to the grid line...THEN hit enter and begin my distance measurement command. No construction lines to erase!
My problem is, I can't figure out how to select the point at which the vertical line intersects the sloped pavement.
I played with polar tracking, which will do that when simply drawing a line. It does not work when you are in tracking mode.
I realize that I could simply offset the zero grid line 16.67' left and measure from the intersection of that line and the finish grade to another grid line to determine the elevation. That would still leave, what I term a "construction line" to erase.
This was just an example of how I might use a construction line.
I am no Civil 3d expert, but one thing I have noticed about it is that it has the ability to do alot in surface models. Meaning you are probably able to do what you want by creating a corridor surface of your road, and then take off elevations from it.
One of my old party chiefs said using Civil 3d for surveying is "Like building a sand castle with a bulldozer." I have noticed that if you learn the controls to said bulldozer, it is damn powerful.

Here is a simple example.
I need to stretch the end of my line to a location that is .5' north of the intersection of the blue lines. Typically I would draw a circle with a .5' radius from the intersection, then stretch the line to the upper quadrant. Then erase the circle.
The circle, in this case is my construction line.
Utilizing tracking mode, I can grab the end of the line, type "TK", then pick the intersection of the blue lines, then type .5' and enter while I'm holding a vertical line, then hit enter and the line is stretched to the correct location with no construction lines to draw or erase.
How would you stretch the line without drawing the circle?
You can also have too many routines running in the background on your computer using up too much of your system resources for your screen to keep up with your input on the keyboard.
Do a ctl-alt-del and/or bring up the Windows Task Manager and check on the CPU Usage. If you are not doing any work on any programs and it is a high %, something is working overtime in the background.
Sometimes a reboot will fix it and if it persists you need to clean some garbage out with a root cleaner and spyware utility.
UCS, ENTER, pick elev. 2690 line at centerline, ENTER.
Zoom way into approximate area of your query.
Trace cross section with crosshairs til your coords read -16.67,XX.XX.
In your example, XX.XX divided by 2, plus 2690, is your elevation.
Well, you DID say you use brute force.
UCS, ENTER, ENTER will get you back to real coords.
That is a good trick.
I found that the polar snap allows you to snap to a line (polar projection) to a skewed line, which eliminates trimming over-shoots or stretching lines.
