New to driving - is this normal?

[barleyspicy]

Driving 20mph in a 20mph zone. It's a long stretch of road on my commute to work but all the cars in front speed off and all the ones behind honk their horns.

I'm 100% sure is a 20 zone as there are multiple signs. Is there an unwritten rule that if there are no speed cameras everyone drives faster?

I really don't feel comfortable speeding but it happens most mornings the horns behind me and I feel awful.

If someone is distracting me from behind and also most likely driving without an adequate 2 second gap, or 4 seconds when roads are wet, I would much rather reduce my speed to give additional leeway and should they drive into the back of me because I had to stop suddenly then safer at a slower speed.

People driving aggressively are the dangerous drivers, not defensive driving. Oh and the Highway Code advises when being tailgated to increase your gap to the vehicle in front, which would require reducing your own speed to facilitate this.

I think advising Op to slow to a barely moving crawl of 10mph isn't a safety measure.

It sounds like a busy road at the time op's travelling..It's a passive aggressive gesture and holds up / punishes everyone on that side of the road on their morning commute.

Many years ago, I was approaching a set of lights in my home city. The driver behind was forcing me to faster than I liked. As the liggts changed, I wanted to stop, but he forced me through (if I'd stopped he'd have gone into me).
I got 3 points on my license.
Now, I drive at my speed, although sometimes when I get an arsehole behind me,

I slow down more, just to piss them off (sorry, pressed post too soon).

(I slow down by a couple of mph, not a huge amount).
