Annoys me at times. If I have to down change in the three wheeler, it's a slow process as you cannot rush a double de-clutch. As a result, I often slow rather more than a modern car and of course, it's done with no brake lights as the brakes are not applied.
Last tailgating twit jumped to the outside lane at a roundabout entry, and got utterly burnt off by a car 80 years older. I can make very good starts, and first gear is good for 45mph...
No indicators on my Morgan. I do make hand signals, but I wonder how many motorists actually understand them. The "I am turning left" one is not particularly obvious.
