What are some useful other websites for good reference material?

There is a wide range of information out there on the Internet regarding Tesla products, beyond the Tesla website, forums, and Engage platform. TeslaFi’s firmware tracker has already been mentioned. It also links to the NotATeslaApp website which is a great place to look at release notes and upcoming features.

There are several Reddit channels specific to Tesla, including /r/teslamotors.

There are even other FAQs out there managed by other groups, including http://www.teslamodel3wiki.com.

There are dozens of YouTubers that provide good information on Tesla or other EV vehicles. Examples in no particular order or recommendation are Bjorn Nyland, Car Confections, DaxM, Dirty Tesla, Don’t Waste Your Time (local member), DǼrik, Frugal Tesla Guy, i1Tesla, model3man, Mother Frunker, Tesla Joy, Tesla Raj, Alex Venz, Andy Slye, Because Tesla, Jeremy Judkins, Pure Tesla, Tesla DIY, and Tesla Owners Online.

 

What kind of rebates can I get for owning a Tesla? How about a home charger?

The website https://marylandev.org/incentives/ has a good summary of this information. Some points from that website:

As of January 2022, you will not get any Federal tax rebate for purchasing a Tesla. This may change with legislation currently being mutilated in the sausage-making machine known as Congress; this FAQ will be updated if and as necessary on that topic.

For Maryland, you may get some money back for a charger install. It must be done by a certified electrician with proper permitting, and it has to be obviously for EV charging. A NEMA 14-50 outlet by itself is not enough; a NEMA 14-50 outlet with, say, a Tesla mobile charger is.

There may be some benefits offered by your power company as well. Check with them, but one common warning noted in the group is you may need to give them access to your Tesla account which raises some questions.
