Curved route plugin?

I was wondering if it were possible to make a plugin that curves your routes. i feel the sharp turns are one of the biggest give-aways for a bot. or maybe there is something like that already out there?

 

I would like this too but it isnt possible as you CTM

 

well it would be possible with ctm, but it would give you further problems in tight places(running into stuff/getting stuck/usual)
