On one trip to the UK my rental car was a Mercedes A160 diesel. It was so utterly devoid of power that it was a legitimate death trap when confronting a busy roundabout from a standstill.

European automotive luxury means getting the perfect car from a wide array of choices, including the privilege of being able to choose an engine that makes an economy Toyota hatchback seem downright sporty by comparison.

I'm not sure if you drove in the UK much, but generally roundabouts are explicitly not "death traps" regardless of the amount of power you have. I literally use them on a cycle from time to time. Everyone is slow, pays attention, and is ready to brake if needed. If you feel need for extra power, you're probably doing something wrong (e.g. not giving enough space for the oncoming traffic you're supposed to yield to).

That is certainly the case for the vast majority of roundabouts. But there are also a number of roundabouts which have a large diameter, limited visibility and a continuous flow of fast-moving traffic and you’d be sitting there forever if you couldn’t nip into a small gap. I’ve noticed this in particular while in Kent in the south-east.

(I’ve driven across a decent amount of the UK, from Heathrow to Durham, Edinburgh, King’s Lynn, Greater London and Folkestone. I have an extended array of in-laws in Consett, Snettisham, Isle of Man, and elsewhere.)
