Mapping is hard. My city is close to a perfect grid so mapping apps generally do pretty well here. My biggest frustration with Google Maps recently is how deceptive it’s estimated times are.
For walking, cycling, and transit Google calculates the entire trip. Unfortunately for driving directions it only tells you the optimal time not including parking, getting settled in your vehicle, or getting to your final destination from your parking spot. People see these ridiculous estimations and assume driving is always faster but at the end of the day its faster to take one of the alternatives most of the time in my city.
I recommend getting some bright lights. I have a 350 lumens rear light that makes my bike more visible than most vehicles.
