How Does the Live Speedometer Tool Perform on Long Drives with Tesla Model 3?

I’ve been driving my Tesla Model 3 for a while now, and one thing I’m curious about is how well live speedometer apps function during longer trips. I’ve noticed that some apps, like the live speedometer tool that uses GPS data from your phone, can offer real-time speed tracking in addition to what the car's dashboard already displays. For those who have used similar apps, especially for electric vehicles like the Model 3, how does it handle during extended road trips?

For instance, I’m planning a trip that spans over 300 miles, mostly on highways and some rural roads. I’m interested in knowing if the live speedometer maintains accurate readings throughout the trip, especially when driving through areas with limited GPS signal. Does it sync quickly with the car’s speed, and how reliable is it during quick acceleration or deceleration?

Additionally, with EVs like the Tesla Model 3, the built-in speedometer already provides a lot of real-time data. So, how does the live speedometer tool compare or complement the car's system? Does anyone find it useful for things like monitoring speed on alternative routes or when the Tesla's navigation might not show specific data for speed limits?

I’d also love to hear if anyone has tried this tool on longer journeys that involve crossing different speed zones or when you’re switching from urban roads to highways. Does the live speedometer stay consistent or experience lags? Given that EVs like the Model 3 handle speed differently due to their instant torque, I wonder if this tool picks up on those changes smoothly, especially when switching between driving modes like Chill or Sport.

Lastly, does using a live speedometer tool affect battery consumption on your phone during long trips? I’m planning to keep my phone connected to the car’s charging port, but I’d like to know if others have noticed any impact on phone battery life or GPS accuracy. How often do you find yourself switching between using this tool and just relying on the car's built-in features?

Looking forward to hearing your experiences and tips!
 
The last time I used a GPS vehicle app was to measure acceleration and speedometer offset. Once I had the metrics, I didn't bother. However, I can sympathize with a steering column speedometer.

A former Prius owner, I was well acclimated to dealing with a center mounted speed display. But the "eyes on road" nag sometimes gets in the way. I also like distance measurements to 1/10th of a mile versus the integer metrics Tesla uses. My BMW i3-REx has that in the navigation screen (no nag) and it helps to avoid missing a turn by better lane and deceleration.
