-   * Continuous driving test at EPFL campus starting 20:22 and ending 23:20. +
-   * Free drive until reset: +
-      * 21:00 - 21:15 +

-      * 22:30 - 22:57 +
-      * 22:57 - 23:08 +
-    * Wheel Hub detached from M4 at 23:05 due to vibrational loosening of the set screw. This will be resolved with a bit of Loctite. +

-   * ~2m turning radius was measured +
-   * 218m/h speed was measured +
-   * battery voltage (at room temperature,​ no load): ​  +
-      * beginning: 4.08 V +
-      * end: 3.66 V +
-   * battery voltage (at outdoor temperature (10°C), under driving load) +
-      * beginning: 3.67 V (ADC 8-bit value: 156) +
-      * end: 2.90 V (ADC 8-bit value: 46) --> note that this voltage is below the pre-programmed 20% battery charge level (threshold = 2.95 V (ADC_val = 52)), at which the 11V motor supply voltage is turned off) +
