In the past 18 months I've noticed Google Maps' navigation prompts being announced just slightly too late for comfort; e.g. I'm often nearly into an intersection at 30-40 mph when my phone tells me to turn onto the cross street. In that same 18 month timeframe I've moved to a new city so I'm acutely aware of this lag.
I chalk this up to Google Maps' overall bloat and sluggishness on my 2-year-old phone.
