All modern smartphones allow you to use their LTE signal as a wifi hotspot. The only way I could see the in car wifi as being beneficial is if you get truly unlimited data. (Edit: Chevy claims to have a more powerful antenna than in smartphones so the signal is better. I don't think this matters that much as I have been able to get 50 Mbps down while on the road with my iPhone) OP is wanting to stream Netflix in the car. That's going to be pretty expensive data plan and the quality may not be that great most of the time. Let's say they watch 10 hours of netflix a month (20 minutes a day). that's what, like 15-20 GB? I think AT&T's 15 GB shared data plan starts at $160 a month.

Here are pricing options:

quote:
Pricing depends on whether you subscribe to OnStar’s advisor-based service for the first 3GB of data. After that, pricing is the same for subscribers and nonsubscribers alike.

200 MB: $5 per month (OnStar subscribers); $10 per month (non-subscribers)
1GB: $15 per month (OnStar subscribers); $20 per month (nonsubscribers)
3GB: $30 per month
5GB: $50 per month

One-day use by anyone (OnStar subscriber or not) costs $5 a day for 250MB. A 12 month, 10GB “bucket” of 4G LTE service will cost $150 for OnStar subscribers or $200 for nonsubscribers. Existing AT&T customers can add GM vehicles to their Mobile Share plan for $10 a month.

So you'll be able to pay $50/month for the privilege of streaming 2.5 hours worth of netflix, assuming that 1hr = 2 GB

and here is how much data netflix uses:

quote:
Watching Netflix uses about 1 GB of data per hour for each stream of standard definition video, and up to 3 GB per hour for each stream of HD video. This can create headaches for Netflix members that have a monthly bandwidth or data cap on their Internet service. Below, you'll find a couple of ways to reduce the amount of data Netflix uses, without having to resort to drastic measures (like actually watching less Netflix).

Adjust your data usage settings

Adjusting the data usage settings for your account is the easiest way to reduce the amount of bandwidth used while watching Netflix. There are 4 data usage settings to choose from, each estimate below is per stream:

Low (0.3 GB per hour)
Medium (SD: 0.7 GB per hour)
High (best video quality, up to 3 GB per hour for HD, 7 GB per hour for Ultra HD)
Auto (adjusts automatically to deliver the highest possible quality, based on your current internet connection speed)

So, in short, good luck streaming netflix to your vehicle.
