Depending on how busy the roundabout is, I have to get a bit aggressive. Luckily I can just about keep up with the speed of traffic but yes they are daunting. Really, for new cyclists, I would tell.tbem to take their time and just use the footpath and walk along or something. Its a pita and you should not have to do that but the reality is drivers are I a hurry, you cannot tell which way they will exit, they seem to.be INA n extra hurry lest another driver gets in their way, it's too damn dangerous and until you're confident and fast, I would just stay off.
