MIPAA is a motor industry body that has taken it upon itself to make it easier to see the influence of different brands, drivers and writers within this sector.
The Power Index is an easy way to see who these influencers are. MIPAA released its list of the top 10 motoring writers on Twitter, with Rebecca coming in at number eight!
Rebecca's mix of race-day updates, car reviews and regular insights into her life, makes her very influential across social media as so many people are interested in what she has to say.
These rankings aren't just based on follower counts, however, they also look at engagement. The amount of mentions, retweets and favourites Rebecca gets is also taken into account as it shows that people are listening (reading)!
You can follow Rebecca on Twitter: @RebeccaRacer. She's also active on Facebook and Instagram too.
Take a look at the other influential motoring accounts on Twitter over on the MIPAA website.
For those of you wondering where you'll be able to see Rebecca next, she'll be at Goodwood Revival next weekend and will be racing at Donington on the 19th and 20th September. Watch this space for details.
