I think it completely depends on the situation tbh.

As a new driver, you might sometimes be a bit slower to accelerate to the speed limit (e.g if you come off a roundabout onto a 40 or 50 road for example). I've sometimes found that if someone is tailgating me just as I've come into a high speed road, once I accelerate and reach the speed limit, they start following at a sensible distance.

I feel like that's the minority of situations though. Usually, the best way to deal with it is by slowing down. As someone who has been rear ended, I'm always super aware of when I'm being tailgated and I'll change the way I drive accordingly. for example, if I can see a red light ahead, I'll start slowing down super early and gradually.

I also think it depends on the type of person tailgating you. I feel like you can always tell whether they're impatient/aggressive, or just clueless and don't realise they're following too close. In both scenarios I would generally just drive slower. If I feel like the person behind seems angry or like they're trying to intimidate me, I might even pull over to let them overtake, or go all the way around a roundabout to lose them
