Not really. I once experience car suddenly dead. I restarted and it could move again and drove to nearby workshop. Lucky it was near the workshop. Tested and found out alternator was dead.

When the engine is off, chemical reaction in battery will slowly recharge the battery. I restarted the car and drove home about 1km away. I was lucky it happened not yet far away from home.The next day went to spare part shop to order the alternator. Got it replaced two days later.

Of course car cannot move since no power to spark plug.

Nowadays, you just need to have number for car battery service. Just wait for battery change. No need to tow car to nearest workshop anyway
