TezLab has launched a new feature called 'car report' for its app, catering to Tesla and Rivian electric vehicle owners. This subscription-based service, priced at $5.99 per month, provides users with detailed insights into their driving habits and vehicle performance. Key features include data comparisons with other users and visualizations based on charging behaviors. The update comes after Tesla introduced an official API, enabling TezLab to enhance its offerings. TezLab plans to expand further to other EV brands like Hyundai and Kia, relying on customer subscriptions for growth.
