    isn't prescient. Got caught by an M1 closure due to a police incident
    just past the last junction where we could have exited.

    I watched upwards of twenty vehicles reverse up the on slip road with
    varying degrees of precision and which was still being used by traffic
    unwisely coming down onto the now gridlocked motorway. One of them had
    a collision at the top whilst reversing onto the busy roundabout!

    Usually, the police get very agitated by this sort of thing.

    They've got nothing else to do with their time.

    Not at all. My wife's iPhone provides entirely adequate voice
    instructions about which lane to be in next turn and and how far to
    the next waypoint. It even recalculates if it finds a traffic jam
    ahead.

    Which app does she use for navigation? Many people recommend Waze. I'm

    Google's basic map and routing functionality suffices for us. It
    includes real time traffic updates and shows jams ahead. We have it
    set to only recalculate the route if >15 minutes can be saved.

    not sure if there are better options. One problem I've noticed with
    Waze is that sometimes the GPS seems to stop and the vehicle doesn't
    move on the map. I think others have noticed this with Waze.

    That is most likely a problem with the GPS constellation above you
    (particularly in cities with many high buildings). It needs to see at
    least 4 and preferably 5 satellites to get a reliable position to 10m.
    It is amazing that they can now do this routinely! It involves
    precision time measurements to 30ns resolution to be that accurate.

    Thanks. Useful to know. However, when I have that problem with Waze I
    find that if I switch to a different navigation app, that one works.

    It is usually quite transient and should self correct inside a couple of minutes. You can get some of the e-Trac ones for walking to show you how
    many satellites and an estimate of accuracy on some models. New GPS satellites will cross the sky every 5 minutes or so.

    Every single GPS I've used shows you how many satellites and where they are. What rubbish are you using?

    Again it uses a "nearby" heuristic to snap you onto a footpath if at all possible.

    You use paths? Off the beaten track is a thing you know.

    A police incident? You mean one of those problems caused by the police? It takes 5 minutes to photo the accident then move the cars out of the way of thousands of late for work road users.
