Mini Roundabout Question

[West]

Theres a couple of them in my town centre, I tend to go round them... some on a residential road, and if theres no traffic ill just bump over them..

Generally, if you go slow enough you can drive around the white painted center circle easily in most cars. I take it most here have trouble with the slow bit

Some of the ones round here you would have to slow to about 5mph to go round, and they are on a major road (one was put in so they could have an entrance to a new block of flats - a normal T junction would have been better in my opinion*).
I tend to slow down to about 10mph, but even then it's hard avoiding just going over the white painted bit.

It seems to be the latest fad in screwing up local traffic, putting mini roundabouts in whilst barely widening the road to allow for the roundabout (basically where you used to have the centreline, someone has spilt the pain pot ), or putting in a mini roundabout badly off centred on an existing road to allow a new junction (so traffic coming one way from the existing road basically carries on as normal, whilst traffic going the other way ends up having to go _/@\_ ).



*Given the likely amount of traffic using the new junction/turning during the average day (it's about 100 flats), compared to a major road that must have tens of thousands of vehicles on it every day.
