yes but still in fast reading there is very much noise in output so its necessary to use filter doesnot matter adxl or mpu6050. I have also used mpu6050 and output was noisy plus unstable as there was drift in values so i moved to adxl335 and it seems very stable in my case.
Steven Reubenstone and @team I have implemented PID on filtered accelerometer sensor data in make car move in straight direction only. PID is auto-tuned . And great thing is everything is done on standalone arduino. Simulation results are looking good. I have ready sketch for test run.Lets decide who is going to prototype this car so that we can test code.
