I do like Waze and I find that it is quite accurate in terms of arrival times, usually provides effective routing and I like the live traffic updates. I remember once it took me on what felt like a weird route out of Reading, but it took just ten minutes, whereas if I had taken the route I would have taken without Waze (as I didn’t know Reading very well) it would have taken at least thirty minutes. Waze took me down quieter less busy road, so I was out of Reading very quickly.
Recently though it got very confused when I was travelling on the M4 westbound and then got caught in a traffic jam between junctions 12 and 13. There had been an accident and the lorry involved had spilled its fuel onto the carriageway. The police then closed the motorway, so that it could be resurfaced and directed traffic off at junction 12. Well too late for me as I was already way pass junction 12 and close to junction 13.
Of course with the motorway closed, Waze was updated and the M4 westbound was shown as a red and white dashed line indicating the road was closed. Of course Waze didn’t realise I was heading westbound and just assumed I was on the other carriageway and heading eastbound. So it was inaccurately telling me to head to junction 12 and come off there.
Well I couldn’t as I was stuck westbound.
Eventually after the police started letting traffic through on the outside lane pass the accident, well the fuel spillage, Waze caught up and worked out I was heading westbound after all.
