I couldn’t check live traffic on the TT as my ‘live services’ subscription ended in Dec last year, and I didn’t renew as the new car had the built in Garmin unit.
Anyway. Waze got me there through some very busy traffic on the A1, A720 and M8, and always gave accurate info on where there was slow moving traffic, or the traffic had come to a standstill.
On the return journey, the traffic was much less, and I was able to enjoy the drive much better. The only concern was slowing down fast enough when Waze reported a speed check camera ahead.
