New 70D owner here, did a search without finding anything related. Yesterday, I decided to annoy a bro-truck driver for a bit. Under hard acceleration, I heard a short beep sound and looked down and saw a red line where the blue speed tape indication would be. Only saw it for a second, and I can't say for sure that it replaced the blue, or was just outside of it. The performance of the car felt normal. Has anyone else seen this, or know what I'm talking about? Thanks.
