Electric brushed motor for electric car project
Welcome to Stack Exchange!  A 24-volt, 11 amp motor has an input of 24 * 11 or 264 watts.  Assuming (charitably) 90% efficiency, you have 238 watts of output power. At 5700 rpm, this much power means that you have torque of only 0.4 N-m.  You can probably stall this with your fingers.

A fractional horsepower motor (yours is less than 1/4 hp) is not going to be adequate for a human-sized car.  When the motor is stalled, the current is only limited by the resistance of the windings, and since you are not making any mechanical power, all goes into heat.
