Computer predictions

I have been recently disappointed by Google Maps on a number of continuous occasions. The time that it takes for me to get somewhere has lately been out by more than 10 to 15 minutes. I used to rely on it a lot but now I am hesitant. I am confident I will still get there but their routing seems to not be as efficient as before.

From what I gather the amount of information they receive hasn’t quite changed. Their algorithm might be being tweaked it really is hard to know. However what it made me realise is that using data to project the future should be made extremely clear. It is one thing to know how many cars there are on the road, and another to predict how fast each of them drive.

Don’t base all your decisions on data analysis. There will be things that data models cannot predict and it might be much more important than you think.
